Research Progress on Protein Separation and Purification Materials ZHAO Ya-qi, ZHANG Xin-yue, HUANG Qian, SUN Xue, QIAN Jun-li, DONG Lin-yi* ( School of Pharmacy, Tianjin Medical University, Tianjin 300070, China)
Abstract:Protein separation purification remains a fundamental process in disciplines including biochemistry, biotechnology, and biopharmaceuticals, with its efficiency and quality directly impacting downstream applications. With the rapid advancement of biotechnology, the ongoing development of new materials has enabled more efficient and specific methods for protein purification, driving innovation in this field. This review first summarizes traditional protein separation techniques, including salting-out precipitation, extraction, electrophoresis, dialysis, and chromatography, which have been widely applied and improved in the past few decades. Despite their maturity and reliability, these methods still face challenges such as low sensitivity, poor resolution, and cumbersome operation. Next, the review elaborates on novel protein purification materials along with their application examples. For instance, nanomaterials (e.g., magnetic nanoparticles, carbon nanotubes, carbon quantum dots) exhibit high specific surface area and functionalization capability, which can significantly enhance adsorption capacity and selectivity. Polymeric materials (e.g., molecularly imprinted polymers, functionalized polymer materials) optimize purification efficiency and specificity through their designable structures. Additionally, biomaterials (e.g., polysaccharides, nucleic acid aptamers) enable highly specific target binding while minimizing nonspecific adsorption. Additionally, it provides forword-looking insights into their future development trends, which are anticipated to evolve toward intelligent systems, full automation, and green sustainable solutions. These advancements aim to provide valuable references for further progress and innovation in the field.

摘要:与传统的热裂解和催化裂解工艺相比,结合了烷烃脱氢和酸催化裂解两种活性位的脱氢裂解工艺可以提高石脑油裂解低碳烯烃的产率并降低能耗。为了研究设计新型石脑油脱氢裂解双功能催化剂中脱氢活性位和裂解活性位的协同效应,依据MWW分子筛酸性可调和富含羟基结构的特点,在MCM-22分子筛上通过原子原位移植引入Sn作为路易斯酸脱氢位点,采用沉积沉淀法引入Ni作为金属脱氢活性位,对分子筛的质子酸酸位点与引入Ni和Sn的脱氢活性位点进行了优化组合。引入的Ni颗粒(NPs)被SnOx捕捉形成双金属镶嵌结构增强了路易斯酸强度,这种活性位点之间的协同作用促进了正辛烷脱氢裂解反应,提高了丙烯和乙烯的收率,并实现了对丙烯/乙烯(P/E)比例的控制。结果表明采用原子原位移植法负载Sn,SnCl4会与分子筛骨架中的羟基发生脱氯化氢反应形成SnOx物种,表现出明显的路易斯酸性。沉积-沉淀(DP)法负载的Ni纳米粒子可以被SnOx电荷捕捉进一步增强路易斯酸强度,提高正辛烷转化率、低碳烯烃收率和P/E比。此外SnOx物种在高温反应过程中从分子筛骨架析出为SnO2并包裹Ni纳米颗粒形成核壳结构。这种结构显著减少了脱氢裂解过程中的积炭,提高了催化剂的稳定性。

Synthesis of Low-carbon Olefins by Dehydrocracking of N-octane Catalyzed with Ni-Sn-loaded MCM-22 Zeolite GUO Cheng-xiong, WU Gui-ying, JIN Fang* (School of Chemical Engineering and Pharmacy, Wuhan Institute of Technology, Wuhan, Hubei,Key Laboratory for Green Chemical Process of Ministry of Education, Hubei,Novel Reactor & Green Chemical Technology Key Laboratory, 430205, China)
Abstract: Compared with the traditional thermal cracking and catalytic cracking processes, the dehydrogenation cracking process that integrates the two types of active sites for alkane dehydrogenation and acid-catalyzed cracking can enhance the yield of light olefins from naphtha cracking and reduce the energy consumption. In order to study and design the synergistic effect between the dehydrogenation active sites and the cracking active sites in a novel bifunctional catalyst for naphtha dehydrogenation cracking, based on the characteristics of the adjustable acidity and the hydroxyl-rich structure of MWW zeolites, Sn was introduced as a Lewis acid dehydrogenation site in the MCM-22 zeolite by the atom-planting method, and Ni was introduced as a metallic dehydrogenation active site by the deposition-precipitation method. An optimized combination was made for the proton acidic sites of the zeolite and the dehydrogenation active sites with the introduced Ni and Sn. The introduced Ni particles (NPs) were captured by SnOx to form a bimetallic mosaic structure to enhance the Lewis acid strength and this synergistic interaction between the active sites facilitated the dehydrocracking reaction of n-octane, which increased the yields of propylene and ethylene, and realized the control of propylene/ethylene (P/E) ratio. The results indicate that Sn is loaded by the atom-planting method, SnCl₄ undergoes the dehydrochlorination reaction with the hydroxyl groups in the zeolite framework to form SnOx species, which exhibit distinct Lewis acidity. The Ni nanoparticles loaded by the deposition-precipitation (DP) method can be captured by the charges of SnOx, thereby further enhancing the Lewis acidity, which improves the n-octane conversion, yield of light olefins, and P/E ratio. In addition, SnOₓ species precipitates from the zeolite framework as SnO₂ during the high-temperature reaction and anchors the Ni NPs to form a core-shell structure. This structure significantly reduces the coke deposition and improves the stability of the catalyst.

摘要:通过液相还原法成功制备了Cu2O和氮掺杂材料(CNx)的系列复合光催化材料Cu2O@CNx。采用FT-IR、XRD、SEM、HRTEM、XPS等多种表征手段对材料的结构、形貌和化学组成进行了全面分析。以四环素(TC)为模型污染物,在氙灯光源模拟可见光条件下,系统地考察了四环素降解反应的几个主要影响因素。实验结果表明,在模拟可见光300 W、四环素浓度20 mg/L、催化剂使用量30 mg、溶液pH 6的条件下,Cu2O@CNx-50作为催化剂,120 min后可以使100 mL的四环素降解率达到92%。由此可见,该催化剂在可见光催化领域表现出优异的催化性能。进一步研究了共存阴离子对催化体系的影响,发现NO3-对降解效率影响不大,SO42-浓度低时对催化效果基本无影响,当浓度升高到10 mmol/L时,对四环素的降解起抑制作用。但CO₃2⁻因自由基捕获作用对四环素的降解影响显著,当浓度为5~10 mmol/L时可使降解率下降65%。自由基捕获实验证明了光生空穴(h+)与超氧自由基(·O2−)在四环素降解中起主要作用。最后对Cu2O@CNx-50的稳定性进行了研究,重复使用4次后,TC的降解率有所下降。为开发高效稳定的可见光催化材料提供了新的思路,在环境污染物治理领域具有潜在的应用前景。

Preparation of Cu2O@CNx Material and Its Application in Photocatalytic Degradation of Tetracycline WU Yi-fei, HU Yang, WANG Si-ping, FU Wan-ting, LV Chun-xin*(College of Biological and Chemical Engineering, Jiaxing University, Jiaxing, 314001, China)
Abstract: Cu2O and nitrogen doped (CNx) composite photocatalytic materials Cu2O@CNx was successfully prepared by liquid phase reduction method. The structure, morphology and chemical composition of the materials were analyzed by FT-IR, XRD, SEM, HRTEM and XPS. Using tetracycline (TC) as a model pollutant, the main influencing factors of tetracycline degradation reaction were systematically investigated under simulated visible light irradiation from a xenon lamp The experimental results demonstrate that under conditions of 300 W simulated visible light, 20 mg/L TC concentration, 30 mg catalyst dosage, and pH 6, the Cu2O@CNx-50 catalyst achieve a 92% degradation rate of 100 mL TC solution within 120 minutes. This indicates that the catalyst exhibits excellent photocatalytic performance in the visible light range. Further investigation into the influence of coexisting anions on the catalytic system reveals that NO₃⁻ has little effect on the degradation efficiency, while SO₄²⁻ shows negligible impact at low concentrations but inhibited TC degradation when the concentration increased to 10 mmol/L. Notably, CO₃²⁻ significantly affects TC degradation due to its radical scavenging effect, reducing the degradation rate by 65% at concentrations of 5~10 mmol/L. The free radical capture experiment demonstrated that photo generated holes (h+) and superoxide radicals (O2−) play a major role in tetracycline degradation. Then, the stability of Cu2O@CNx-50 is studied. After repeated use for 4 times, the degradation rate of TC decreases, which may be because the crystal structure of the catalyst shows more carbon peaks after 4 cycles. This work provides a new idea for the development of efficient and stable visible light catalytic materials, and has potential application prospects in the field of environmental pollution control.

摘要:橄榄石型LiFePO4材料因其高理论容量(170 mAh/g)、优异的热稳定性、环境友好和低成本等优点而成为目前动力电池主要正极材料。然而LiFePO4较低的工作电压(3.4 V vs. Li+/Li)导致其能量密度不高,同样具有橄榄石型结构的LiMnPO4的工作电压达到4.1 V,因而具有更高的能量密度,可是LiMnPO4的循环稳定性差。铁掺杂的LiFe0.4Mn0.6PO4/C正极材料结合了LiFePO4和LiMnPO4的优点,具有高能量密度、良好的循环稳定性和安全性等优势,因而成为当今正极材料研究的热点材料之一。然而,要实现其大规模商业化应用,仍需进一步提高LiFe0.4Mn0.6PO4/C材料的倍率性能和循环寿命。为了解决这些问题,研究人员发现构建多孔结构和碳包覆是最有效的方法之一。为此,采用葡萄糖辅助溶剂热法来构建多孔LiFe0.4Mn0.6PO4/C材料。对比研究两种水热法来制备LiFe0.4Mn0.6PO4/C材料,发现葡萄糖辅助溶剂热法能得到棒状、纳米结构的多孔LiFe0.4Mn0.6PO4/C材料,并表现出优异的电化学性能。在0.1、0.2、0.5、1和2 C时,放电比容量分别达到140.1、130.6、118、106.1和88.9 mAh/g,在1 C倍率下充放电循环100次后保持率达94.7%。这说明在溶剂热法基础上加入一定量的葡萄糖辅助,可以调控制备多孔LiFe0.4Mn0.6PO4/C纳米材料,并能显著改善其倍率性能和循环性能。

Prepation Porous LiFe0.4Mn0.6PO4/C Cathode Material by Glucose Assisted Solvothermal Method Liu Zhang-bin1,2, Li Ji-lan*2 (1.School of Environmental and Chemical Engineering, Dalian University, Dalian 116622, China; 2.

Abstract:Olivine type LiFePO4 material has become the main positive electrode material for power batteries due to its high theoretical capacity (170 mAh/g), excellent thermal stability, environmental friendliness, and low cost. However, the lower operating voltage of LiFePO4 (3.4 V vs. Li+/Li) results in a lower energy density. Similarly, LiMnPO4 with an olivine structure has an operating voltage of 4.1 V, resulting in a higher energy density. However, LiMnPO4 has poor cycling stability. The iron doped LiFe0.4Mn0.6PO4/C material combines the advantages of LiFePO4 and LiMnPO4, with high energy density, good cycling stability, and safety, so it has become one of the hot materials in the cathode materials of lithium-ion batteries. However, the rate performance and cycle life of LiFe0.4Mn0.6PO4/C material still need to be further improved before it can be commercially applied. To address these issues, researchers have found that constructing porous structures and carbon coating is one of the most effective methods. For this purpose, glucose assisted solvothermal method was used to prepare porous LiFe0.4Mn0.6PO4/C material in this content. Comparing two hydrothermal methods for preparing LiFe0.4Mn0.6PO4/C materials, it was found that LiFe0.4Mn0.6PO4/C materials prepared by glucose assisted solvothermal method showed rod-shaped and porous nanostructure, which exhibit excellent electrochemical performance, at 0.1、0.2、0.5、1 and 2 C, the discharge specific capacities reached 140.1、130.6、118、106.1 and 88.9 mAh/g, respectively. After 100 charge-discharge cycles at 1 C rate, the retention reached 94.7%. This demonstrates that the structure and morphology of the LiFe0.4Mn0.6PO4/C can be controlled and the rate performance and cycling performance can be significantly improved through glucose-assisted solvothermal synthesis.

摘要:硫化亚锡(SnS)具有理论容量高、层间距大以及电压平台低等特点,被视为是极具应用前景的钠离子电池(SIBs)负极材料之一。然而,SnS较差的本征导电性及其在循环过程中严重的体积变化,极大地限制了其应用。采用原位生长策略,分别以锡酸钾、六水合氯化钴和硫代乙酰胺为锡源、钴源和硫源,成功制备出氮化硼(BN)负载的SnS-Co1-xS异质结构负极。利用扫描电子显微镜、透射电子显微镜、X射线衍射和X射线光电子能谱等表征手段,对合成材料进行形貌、结构表征。利用循环伏安测试、恒流充放电测试、阻抗测试和恒电流间歇滴定技术,研究材料的电化学性能和电化学动力学。实验结果表明,BN的引入降低了SnS纳米片的厚度,促进了SnS和Co1-xS的均匀分散,提供了丰富的SnS-Co1-xS界面,增强了SnS与Co1-xS之间的相互作用和电荷转移,从而改善了SnS的本征导电率,并促进了其电化学动力学。所制备的SnS-Co1-xS/BN电极在2 A/g的电流密度下,比容量为433.9 mAh/g;在0.5 A/g的电流密度下循环200次,比容量高达496.4 mAh/g,表现出较好的倍率性能和循环稳定性。该研究成果提出了一种构筑高性能SnS负极的新策略。

Preparation and Sodium Storage Performance of BN Supported SnS-Co1-xS Heterostructure XU Ming-yuan1,2, WANG Li-juan*1, LIU Gui-long*2(1.

Abstract: Tin sulfide (SnS) is regarded as one of the most highly promising anode materials for sodium-ion batteries (SIBs) due to its high theoretical capacity, large interlayer spacing, and suitable voltage platform. However, the poor intrinsic conductivity and the severe volume expansion of SnS during the cycling process have significantly restricted its further application. Boron nitride (BN) supported SnS-Co1-ₓS heterostructures were obtained via an in situ growth strategy using potassium stannate, cobalt chloride hexahydrate, and thioacetamide as the tin, cobalt, and sulfur sources. The morphology and structure of the synthetic materials were characterized by scanning electron microscope, transmission electron microscope, X-ray diffraction spectrometer, and X-ray photoelectron spectroscopies. The electrochemical performance and electrochemical kinetics of the materials were analyzed through cyclic voltammetry, galvanostatic charge/discharge, impedance, and galvanostatic intermittent titration techniques. The experimental results verified that the introduction of BN reduced the thickness of SnS nanosheets and promoted the uniform dispersion of SnS and Co1-xS, which provided abundant SnS-Co1-xS interface and enhanced the interaction and charge transfer between SnS and Co1-xS, thereby improving the intrinsic conductivity of SnS and accelerating its electrochemical kinetics. As a result, the prepared SnS-Co1-xS/BN delivered a specific capacity of 433.9 mAh/g at a high current density of 2 A/g and maintained a high specific capacity of 496.4 mAh/g after 200 cycles at 0.5 A/g, showing excellent rate performance and high cycling stability. The research provided a new strategy for constructing high performance SnS anode for SIBs.

Abstract: Acetaminophen (PCT) is a common ingredient in antipyretic and analgesic drugs for the treatment of cold and fever and the relief of various pains. However, excessive intake can cause toxic hepatitis, making it urgent to development a rapid, accurate, and cost-efficient detection method. Given the structural characteristics of PCT, constructing a PCT electrochemical sensor is an effective solution. Cyclic voltammetry (CV) is one of the important techniques to research coupled homogeneous electrochemical reactions, which is valuable for revealing the electrochemical behavior of pharmaceutical compounds and developing highly sensitive electrochemical sensor. In this study, the electrochemical response mechanism of PCT was systematically investigated using CV with a bare glassy carbon electrode in both pH 2.4 and 6.4 disodium hydrogen phosphate-citric acid buffer system and 1.80 mol/L sulfuric acid system. The oxidization mechanism of PCT was elucidated, non-electrochemically active substances were identified, and the evidence of coupled homogeneous electrochemical reactions of PCT in sulfuric acid medium was observed. The results showed that the electrochemical behavior of PCT is strongly influenced by the acidity of the medium. Based on these findings, a PCT electrochemical sensor was developed using a bare glassy carbon electrode. The performance parameters of the electrochemical sensor, such as the linear range, the detection limit, the sensitivity and the selectivity, were determined. It was successfully applied to detect PCT in commercial paracetamol tablets, confirming adequate content levels. This method has the advantages of simplicity, speed and accuracy. Additionally, this study provides a key experimental insights into the electrode process dynamics of aromatic organic small molecules and complements existing method for the rapid detection in pharmaceutical applications.

In recent years, zirconium phosphate, a new type of nanomaterial, has attracted more and more attention due to its unique physical and chemical properties. In this paper, the crystal morphology, preparation methods and application fields of zirconium phosphate nanomaterials are described. There are various preparation methods for micro-nano structured zirconium phosphate materials. At present, the synthesis methods that have attracted much attention mainly include the sol reflux method, hydrothermal method and coordination method. Among them, the sol reflux method is simple and suitable for the preparation of layered zirconium phosphate, which can obtain materials with uniform particles and high purity. The hydrothermal method can synthesize zirconium phosphate at lower temperatures. In recent years, coordination synthesis has attracted much attention due to its high efficiency and energy saving. It can obtain products with good crystallinity and narrow particle size distribution in a short time. Zirconium phosphate has a wide range of application fields. In the environmental field, it can be used to remove heavy metal ions, radioactive nuclear waste and organic pollutants in sewage, showing good adsorption performance. In addition, zirconium phosphate also shows important application value in biomedicine, ion exchange, catalyst, antibacterial material and metal surface coating.

Abstract:PAHs, as a class of typical persistent organic pollutants, are widely present in aquatic environments. They exhibit strong carcinogenicity, mutagenicity, and ecotoxicity, posing significant threats to both the environment and human health. This study developed a method based on recyclable magnetic composite materials (NiFe₂O₄/SiO₂@PDA) combined with magnetic solid-phase extraction (MSPE) and gas chromatography-mass spectrometry (GC/MS) for the determination of 16 PAHs in water. Through optimization of experimental conditions, the optimal extraction parameters were determined as follows: magnetic material dosage of 0.05 g, sample volume of 15.0 mL, V(n-hexane):V(acetone) = 1:1 as the desorption solvent, vortex extraction for 0.5 min, and desorption for 1.0 min. Method validation results showed that the linear correlation coefficients (r) for the 16 PAHs were all ≥0.9995, with LOD were 80~20 ng/L and the RSD were <5.0%. In spiked experiments with real water samples, the average recovery rates for surface water and industrial wastewater were 88.0%~114 %, with RSDs were 1.5%~5.5 %. Additionally, after six cycles of reuse, the recovery rates of the target compounds remained above 90%. Compared to methods reported in the literature, this approach reduces the extraction time to 0.5 minutes, improving efficiency by 30 to 120 times, while maintaining excellent precision and accuracy. This method features simple and rapid pretreatment steps, low solvent consumption, and good reproducibility, making it suitable for the efficient detection of trace PAHs in water. It provides a reliable and environmentally friendly analytical technique for environmental monitoring.

摘要:旨在建立一种适用于复杂锌镍合金镀液体系的锌离子精确定量方法,以突破传统分析技术在该领域的局限性。针对锌镍镀液成分复杂、镍离子干扰显著及配位剂封闭效应等技术瓶颈,创新性地将库仑滴定法与优化标准加入法相结合,构建了基于[Fe(CN)6]4−-Zn2+沉淀反应的电化学分析体系。该方法通过向待测样品中精确添加过量锌标准溶液,实现双重优化机制:其一,过量锌离子与溶液中共存镍离子形成竞争性沉淀,有效抑制镍离子对锌测定的干扰;其二,饱和配位剂浓度消除其对指示剂的封闭作用,从而省去传统方法的繁琐预处理步骤。通过构建锌标准溶液内标体系,建立库仑滴定终点时间与锌浓度的线性响应关系,采用内标换算方法消除溶液基质效应。研究结果表明,该优化方法不仅显著提高了锌镍镀液中锌含量测定的准确性和效率,还展现出对复杂工业样品体系的强适应性。通过双重控制策略(锌镍物质的量浓度比阈值≥10与标准锌物质的量添加比例1.5~5),成功解决了共沉淀干扰和配位剂封闭的行业难题。为电镀液在线监测技术的开发提供了理论基础,对提升锌镍合金电镀工艺的质量控制具有重要应用价值。

Application of Coulometric Titration for the Determination of Zinc Content in Zinc-Nickel Plating Solutions WANG Yan1a, HU Cai-wei1b, CAI Jun-jun1b, HE Peng1a, TANG Jun-rong2, CHENG Cheng2, ZHU Zhi-wei*1b(1a.

Abstract: This study presents a novel analytical strategy for precise zinc ion quantitation in complex zinc-nickel plating solutions, overcoming the limitations of conventional techniques in this field. Targeting technical bottlenecks such as solution complexity, nickel ion interference, and ligand blocking effects, we integrated coulometric titration with an optimized standard addition method, establishing an electrochemical analysis system based on the [Fe(CN)6]4--Zn2+ precipitation reaction. The dual optimization mechanism involves: (i) competitive precipitation suppression of nickel interference through excess zinc addition, and (ii) saturation of ligand binding sites to eliminate indicator blocking, thereby eliminating tedious pretreatment procedures. An internal standard system using zinc standards enabled linear calibration between coulometric titration endpoint time and concentration, with matrix effects corrected through internal standard conversion algorithms. The optimized method not only significantly enhances accuracy and efficiency for zinc determination in industrial plating solutions, but also shows strong adaptability to complex industrial sample systems. By implementing dual control strategies (Zn/Ni molarity ratio ≥ 10 and standard addition ratio 1.5~5), we resolved co-precipitation interference and ligand blocking challenges. This work provides theoretical foundations for developing online monitoring technologies, offering practical value for quality control in zinc-nickel alloy electroplating processes.

摘要:槲皮素是一种存在于中草药、水果和蔬菜中的天然黄酮类化合物,具有抗氧化、抗炎等生物学特性。然而,槲皮素的过量摄入会对人体造成危害,因此探索一种简便、快速、有效的检测方法测定食品中槲皮素的含量至关重要。以金属有机框架MOF-808(Zr)为载体,有机荧光分子四苯基吡嗪衍生物(TPP)为荧光基团,采用沉淀聚合法制备了一种可用于槲皮素检测的表面分子印迹荧光传感器(MOF-808-TPP@SMIPs)。采用傅里叶变换红外光谱、扫描电子显微镜及X射线衍射等技术对传感器进行表征,表明已经成功合成。传感器在较短时间内可以实现槲皮素的吸附平衡。在检测槲皮素时,其荧光强度比值(F0/F)与槲皮素在0.6 ~ 10 μmol/L的浓度范围内呈现良好的线性关系(相关系数R2=0.9983),检出限为0.18 μmol/L。此外,MOF-808-TPP@SMIPs具有高选择性、良好的重复使用性和稳定的荧光性能等特点。采用本传感器对实际样品进行检测时,槲皮素的回收率为86.78% ~ 107.65%,相对标准偏差为1.08% ~ 5.50%,表明其可以用于实际样品中槲皮素的检测。该研究为槲皮素的高效快速检测提供了一种可行的方法。

Preparation of MOF-808(Zr)-Based Surface Molecularly Imprinted Fluorescence Sensor for Quercetin Detection WANG Yu, LI Yuan-yuan*, HUANG Hao-zhan, XING Jian-ping, WANG Tian-cong, WANG Xi, ZHANG Xi-ying, NIU Hao-yu, HE Juan (School of Chemistry and Chemical Engineering, Henan University of Technology, Zhengzhou 450001, China)
Abstract: Quercetin is a natural flavonoid compound found in Chinese herbal medicines, fruits and vegetables, which has biological properties such as antioxidation and anti-inflammation. However, excessive intake of quercetin can cause harm to the human body. Therefore, it is of vital importance to explore a simple, rapid and effective detection method for determining the content of quercetin in food. By using metal-organic framework MOF-808(Zr) as the carrier, tetraphenylpyrazine derivative (TPP) as the fluorophore, a surface molecularly imprinted fluorescence sensor (MOF-808-TPP@SMIPs) for quercetin detection was prepared by precipitation polymerization. The sensor was characterized by Fourier-transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), and X-ray diffraction (XRD), which confirmed the successful preparation of the sensor. The sensor can achieve the adsorption equilibrium of quercetin in a relatively short period of time. The fluorescence intensity ratios (F0/F) showed a linear relationship with the concentrations of quercetin in the range of 0.6~10 μmol/L (R²=0.9983) with a detection limit of 0.18 μmol/L. The sensor also exhibited the advantages of high selectivity, excellent reusability, and good fluorescence stability. The recoveries of quercetin in real samples detected by this sensor ranged from 86.78% to 107.65% with the relative standard deviations of 1.08%~5.50%, which indicated that it can be apply in the detection of quercetin in real samples. This study provided a feasible method for efficient and rapid detection of quercetin.

Abstract: In order to determine the release of 30 kinds of organic acids from mainstream cigarette smoke efficiently and accurately, a novel method for simultaneous determination of 30 volatile organic acids, including formic acid, acetic acid, crotonic acid, oleic acid, furoic acid, stearic acid and eicosic acid, was developed by using polar DB-FFAP capillary column based on vortex extraction combined with gas chromatography-mass spectrometry (GC/MS). In the standard smoking mode, the TPMs of cigarettes were captured by Cambridge filter, and the internal standard of trans-2-hexenic acid and hexanoic acid-d31 were added, then extracted by methanol vortex oscillation, and quantitatively analyzed by GC/MS in the selective ion monitoring mode. The LOD and LOQ of 30 organic acids were 0.012~0.96 μg/ branch and 0.01~3.2 μg/ branch, respectively, and the good linear relationships were presented in the linear range (R2≥0.999). The recoveries and the relative standard deviations(RSD%) of 30 organic acids were 91.1%~106.6% and 0.4%~7.9%, respectively. The method is simple, efficient and sensitive, and is suitable for the determination of the release amount of 30 volatile and semi-volatile organic acids such as formic acid, acetic acid, crotonic acid, oleic acid, furoic acid, stearic acid and eicosic acid in the particle phase of the mainstream smoke of different types of cigarettes. It can accurately control the design of tobacco material parameters and the influence of the amount of tobacco flavors and spices used in different formulations on the organic acid release amount of cigarette smoke. It provides key technical support for cigarette product design, independent aroma modulation and style characteristic evaluation.

Abstract:A UHPLC-MS/MS-QAMS method was established for simultaneous determination of protopine,tetrahydropalmatine,glaucine and corydaline in Jindanfuyan granules. Ultra-high-performance liquid chromatography was adopted with a Waters BEH C18 (2.1×100 mm,1.7 μm) column,and the mobile phase consisted of acetonitrile and 0.1% formic acid containing 5 mmol/mL ammonium formate.The flow rate was set at 0.3 mL/min with gradient elution. The mass spectrometry equiped an electrospray ionization source, positive multi-reaction monitoring mode, and the monitored ion pairs were: protopine 354.3/188,tetrahydropalmatine 356.2/192,glaucine 356.3/325.1 and corydaline 370.2/191.8. Using tetrahydropalmatine as the internal reference substance, the relative standard deviations of the relative correction factors measured by two brands of liquid chromatography - mass spectrometry (LC - MS) instruments and three brands of chromatographic columns were calculated as the factor for the durability investigation. The contents of four alkaloid components were calculated by the quantitative analysis of QAMS method, and the results were compared with those obtained by the external standard method. The four alkaloids have a good linear relationship in the concentration range of 10~1000 ng/mL (r > 0.9961). The reproducibility and recovery of the four alkaloids are within the acceptable ranges. The contents of the four alkaloids are no significant differences between the QAMS and the external standard method. The method has good durability with methodological evaluations with high sensitivity,good specificity and the advantages of short test time. It can be used for the determination of protopine,tetrahydropalmatine,glaucine and corydaline in Jindanfuyan granules.
