摘要： 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K3Fe(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。

Abstract: Asimple UV-visible, circular dichroism thin-layer spectroelectrochemical cell with long optical path has been designed and characterized. The cell with 10 mm quartz cuvette as the optical window, two pieces of 5 mm×10 mm×15 mm teflon as the electrode supporters and a glassy carbon slide as the working electrode has an adjustable thickness of thin-layer. We have carried out the optical and electrochemical experiments of characterization with K3Fe(CN)s and tyrosine working system, which show the cell has a very good thin-layer electrochemistry character and fast spectroelectrochemistry response. The cell can also be used in circular dichroism electrochemistry study.

Key words: UV-visible spectroscopy. Circular dichroism, Long optical path thin-layer cell, Ty-rosine, Spectroelectrochermstry
