UV-vis reflection spectroelectrochemistry has proven to be a very useful multiresponse technique to evaluate the quality of bismuth films obtained by electrochemical deposition on glassy carbon electrodes (GCEs). Bismuth films have recently emerged as a promising and environmental friendly alternative to mercury electrodes for stripping analysis. Spectroelectrochemical measurements, carried out in a flow cell, allowed us to follow in situ the electrodeposition and stripping of bismuth and cadmium. Electrochemical and spectroscopic responses individually have led to successfully quantify the amount of cadmium in test solutions.
紫外可见反射光谱电化学已被证明是一种非常有用的多响应技术，可用于评估通过电化学沉积在玻碳电极（GCE）上获得的铋膜的质量。铋膜最近已成为一种有前途的、环境友好的替代汞电极用于溶出分析的材料。在流动池中进行的光谱电化学测量使我们能够原位跟踪铋和镉的电沉积和溶出过程。电化学响应和光谱响应单独都已成功地对测试溶液中的镉含量进行了定量。
