水杨醛肟电化学修饰玻碳电极及其应用

Study on Electrochemically Salicylaldoxime Modified Glassy-carbon Electrode and Its Application

本文报道用电化学法制作水杨醛肟修饰玻碳电极。研究铜在该电极上阳极溶出伏安特性。电极灵敏度比未修饰玻碳电极提高30倍以上。可用于水中痕量铜的测定,回收率为99～105%。

A salicylaldoxime modified glassy-carbon electrode was prepared by electroch- emical method.The behaviour of copper(Ⅱ)on this electrode was investigated by anodic stripping voltammetry.The sensitivity of this electrode for copper(Ⅱ)is about 30 times higher than that of unmodified glassy-carbon electrode.The electrode was applied to the determination of copper(Ⅱ)in water,and it shows a 99～105% recovery.
