摘要
本文报道一种新的长光程薄层光谱电化学池。采用电极体插入式结构,入射光与电极表面平行。池体结构不用任何粘接剂,可用于多种溶剂体系。结构简单,装配方便。容易清洗及更换处理工作电极与溶液,以水溶液中K_3Fe(CN)6的氧化还原反应进行了表征。
A simple thin-layer spectroelectrochemical cell is de(?)igned for in-situ light tran-sparent and fluorescence measurements. The cell body-photo windows is a piece of 10 mm diameter quartz tubing sitting on a glassy carbon(GC)plate working electrode. A Teflon salt bridge is plugged into the tubing against the GC plate to define a thin layer chamber of 0. 1～0. 2mm thickness. Electrochemical and optical responses of potassium ferrieyanide redox reaction in aqueous solution is reported for the charactcrization.
