聚乙烯醇修饰电极的研制及应用

Preparation of Polyvinyl Alcohol Modified Electrode and Its Application

本文提出用玻碳电极为基体制作聚乙烯醇(PVA)修饰电极。研究了铜在该电极上的阳极溶出伏安特性。探讨了电极修饰及其作用机理。电极可用于水中痕量铜的测定,灵敏度比未修饰玻碳电极提高一个数量级以上。

The polyvinyl alcohol (PVA) modified electrode has been prepared on the basis of glassy carbon electrode. The anodic stripping voltammetric characteristics of Cu (?) on PVA modified electrode is studied. The modification and reaction mechanism of the electrode is discussed. The electrode can be applied to the determination of trace Cu (?) in water, and its sensitivity is about 10 times higher than that of unmodified glassy carbon electrode.
