摘要

利用丝网印刷碳电极(SPCE)对咖啡酸进行了选择性测定,从而获得了一种可靠、可扩展、成本低廉且分析性能更高的电化学方法。首先用 KOH 溶液通过线性扫描伏安法激活 SPCE,然后用环糊精对其进行电化学接枝。pH 值为 8.1 的布里顿-罗宾逊缓冲液(BRB)对咖啡酸氧化有明显的电催化作用,这表明在循环伏安法和方波伏安法(SWV)研究中,与活化电极相比,活化电极的电流响应更大。在理想条件下,活化 SPCE 的 SWV 波产生了线性校准曲线,检出限(LoD,4 sb/m)和定量限(LoQ,11 sb/m)分别为 0.38 M 和 1.1 M。

Determination of Caffeic acid in Cigarette Smoke and Urine by Electrochemical Methods Using Supramolecular Electroactive Materials grafted in Screen Printed Carbon Electrode
Selective determination of caffeic acid, was carried out by using Screen Printed Carbon Electrode (SPCE) to give a reliable, scalable, and inexpensive electrochemical method with enhanced analytical performance. SPCE was first activated by linear sweep voltammetry using KOH solution, followed by its electrochemical grafting with cyclodextrins. Britton Robinson buffer (BRB) solution having pH 8.1, demonstrated a clear electrocatalytic impact towards caffeic acid oxidation, which indicated a greater current response compared to the activated electrode in the cyclic voltammetric and square wave voltammetric (SWV) investigations. The SWV waves at the activated SPCE was used under ideal conditions to produce a linear calibration curve with detection limits of (LoD, 4 sb/m) and quantification limits of (LoQ, 11 sb/m) of 0.38 M and 1.1 M, respectively.

期刊介绍: Oriental Journal of Chemistry was started in 1985 with the aim to promote chemistry research. The journal consists of articles which are rigorously peer-reviewed. The journal was indexed in Emerging Science citation index in 2016. The Editorial board member consists of eminent international scientist in all fields of Chemistry. Details of each member and their contact information is mentioned in website. The journal has thorough ethics policies and uses plagiarism detection software(ithenticate) to screen each submission. The journal has recently partnered with publons as a part of making our reviews more transparent. The journal has recently incorporated PlumX for article level matrix. The journal is promoting research on all social and academic platforms mentioned in PlumX guidelines. The journal uses google maps to improve on the geographical distribution of Editorial board members as well as authors.
