摘要

本研究旨在开发 MWCNT@Ni-BTC 金属有机框架改性玻璃碳电极,用于制备测量左氧氟沙星的简单电化学方法。复合改性剂是通过一步溶热法合成的。使用扫描电子显微镜和傅立叶变换红外光谱对电极表面改性剂进行了表征。同时使用这两种微粒可显著提高左氧氟沙星的氧化电流(3.2 倍),从而有助于对其进行痕量测量。修饰电极上的氧化电流由扩散控制,左氧氟沙星的扩散系数为 1.2 × 10-6 cm2 s-1。该方法的线性动态范围为 2.0 至 100.0 µmol L-1,检出限为 0.2 µmol L-1。测量 20.0 µmol L-1 左氧氟沙星的相对标准偏差为 2.8%(n = 6),15 天内观察到氧化电流下降不到 5%。改良电极被成功用于测定尿样中的左氧氟沙星。

Fabrication of MWCNT-nickel MOF modified glassy carbon electrode for voltammetric determination of levofloxacin

In this research, the aim is to develop MWCNT@Ni-BTC metal–organic framework–modified glassy carbon electrodes for the preparation of a simple electrochemical method to measure levofloxacin. The composite modifier was synthesized via the one-step solvothermal method. The electrode surface modifiers were characterized using scanning electron microscopy and FT-IR. The concurrent application of these two particles notably enhances levofloxacin oxidation current (3.2 times), facilitating its measurement at trace levels. The oxidation current on the modified electrode was controlled by diffusion, and the diffusion coefficient of levofloxacin was determined to be 1.2 × 10−6 cm2 s−1. The proposed method had a linear dynamic range from 2.0 to 100.0 µmol L−1 of levofloxacin and a detection limit of 0.2 µmol L−1. The relative standard deviation for measuring 20.0 µmol L−1 of levofloxacin was obtained at 2.8% (n = 6), and less than a 5% decrease in oxidation current was observed within 15 days. The modified electrodes were successfully utilized for the determination of levofloxacin in urine samples.

期刊介绍: The Journal of Solid State Electrochemistry is devoted to all aspects of solid-state chemistry and solid-state physics in electrochemistry. The Journal of Solid State Electrochemistry publishes papers on all aspects of electrochemistry of solid compounds, including experimental and theoretical, basic and applied work. It equally publishes papers on the thermodynamics and kinetics of electrochemical reactions if at least one actively participating phase is solid. Also of interest are articles on the transport of ions and electrons in solids whenever these processes are relevant to electrochemical reactions and on the use of solid-state electrochemical reactions in the analysis of solids and their surfaces. The journal covers solid-state electrochemistry and focusses on the following fields: mechanisms of solid-state electrochemical reactions, semiconductor electrochemistry, electrochemical batteries, accumulators and fuel cells, electrochemical mineral leaching, galvanic metal plating, electrochemical potential memory devices, solid-state electrochemical sensors, ion and electron transport in solid materials and polymers, electrocatalysis, photoelectrochemistry, corrosion of solid materials, solid-state electroanalysis, electrochemical machining of materials, electrochromism and electrochromic devices, new electrochemical solid-state synthesis. The Journal of Solid State Electrochemistry makes the professional in research and industry aware of this swift progress and its importance for future developments and success in the above-mentioned fields.
