Adsorptive Stripping Voltammetry in a Flow-through Thin Layer Cell for the Determination of Chloramphenicol in Fish Meats

Abstract

论文研制了一种半流动薄层电解池,该电解池采用玻碳为工作电极,对玻碳电极表面活化过程和活化后的玻碳电极对氯霉素的吸附作用进行了研究,建立了半流动薄层吸附伏安法,并成功地将该方法用于鱼肉氯霉素残留的快速检测。本论文共分四章。第一章分别介绍了薄层电化学和吸附伏安法的原理、特点、应用以及氯霉素的各种检测方法,提出本文研究半流动薄层吸附伏安法并将其用于鱼肉中氯霉素残留快速检测的技术路线和创新意义。第二章介绍了所研制的半流动薄层电解池,利用该电解池对氯霉素在更宽电位范围(相对于汞电极)内的电化学行为进行了初步探讨,并研究了薄层池的结构(电极面积、薄层厚度)对氯霉素伏安行为的影响。第三章分为两节:第一节考察...A flow-through thin layer cell is designed and fabricated. A rapid and sensitive method, based on the adsorptive accumulation of chloramphenicol at the electrochemically pretreated glassy carbon electrode in the above mentioned thin layer cell, for determination of chloramphenicol residues in fish meats has been developed. Chapter one presents a brief overview of thin layer electrochemistry, ad...学位:理学硕士院系专业:化学化工学院化学系_分析化学学号:20012500
