铋膜电极的制备及在重金属离子分析中的应用

Research Progress in Application of Bismuth Film Electrode for Heavy Metal Ions Detection

在介绍溶出伏安法基本原理基础上,列举了铋膜电极主要的制备方法,其中预镀铋膜法操作简单,可以通过改变条件来控制制备的过程,因而应用较为广泛。最后简述了使用不同基体材料制备的铋膜电极检测重金属离子及复合铋膜电极在重金属离子检测中的应用,其检出限可达到纳克级,有望实现对环境水的现场监测。

On the basis of introducing the principle of stripping voltammetry, enumerated the preparation methods of bismuth film electrodes. Among these methods, the Bi FE was widely used because the operation was simple and the process can be controlled by changing the conditions.Finally, expounded the use of different substrate material of bismuth film electrodes in the determination of heavy metal ions, and applying the bismuth film electrode complex electrodes in the determination of heavy metal ions. The detection limits of ppb level was achieved.
