设计了一种简易实用的长光程薄层光谱电化学池,该池以10mm石英比色槽为光学窗,2块5×10×50mm的聚四氟乙烯块为电极支承体,玻碳片为工作电极,且薄层厚度可调。以K_3Fe(CN)_6和L-酪氨酸为工作体系进行光谱和电化学实验表明,该池具有良好的薄层电化学特征。对于水溶液,在大于220nm波长内给出良好的光谱和较快的光谱电化学响应,可方便地用于圆二色谱-电化学研究。 A simple and practical long-path thin-film spectrometer electrochemical cell was designed. The cell was a 10 mm quartz cell with an optical window and two 5 × 10 × 50 mm polytetrafluoroethylene (PTFE) For the working electrode, and the thickness of the thin layer can be adjusted. Spectra and electrochemical experiments with K_3Fe (CN) _6 and L-tyrosine as working system showed that the cell has good thin-layer electrochemical characteristics. For aqueous solutions, good spectral and fast spectral electrochemical responses are obtained at wavelengths greater than 220 nm and are conveniently used for circular dichroism-electrochemical studies.
