报道了一种多功能的薄层光谱电化学池设计及其基本表征。该电化学池光窗以内径 15mm石英管为全方位光窗 ,下部安装直径 15mm的玻碳盘工作的电极 ,上部塞进可旋动的聚四氟乙烯参比电极与之相对构成圆盘形薄层腔 .薄层厚度很容易在 0 .1～ 1mm间调节 .能进行薄层伏安、长光程现场紫外 -可见吸收光谱、现场荧光光谱及电致化学发光的检测 ,还可以用于对物质进行电位选择性光谱定量测定 .该电池结构简单、容易拆卸、薄层厚度可调、试剂用量少、灵敏度高、易于操作 .本文用K3 Fe(CN) 6的KCl溶液对不同薄层厚度下的紫外 -可见光谱电化学行为进行了表征
A multifunctional thin-film electrochemical cell design and its basic characterization were reported. The electrochemical cell window with an inner diameter of 15mm quartz tube for the all-optical window, the lower part of the installation of a diameter of 15mm glassy carbon electrode electrode, the upper part of the screw into the PTFE reference electrode with the relative form of a disc-shaped Thin layer cavity.The thickness of the thin layer can be easily adjusted from 0 to 1 ~ 1mm.It can be used for the detection of thin-film voltammetry, long-path UV-Vis absorption spectrum, fluorescence spectra on site and electrochemiluminescence. It can also be used in The material was measured by potentiometric selective spectrophotometry.The cell structure is simple and easy to disassemble, the thickness of the layer is adjustable, the amount of reagent is less, the sensitivity is high, easy to operate.In this paper, K3 Fe (CN) 6 KCl solution on different thin layers Thickness UV-Vis spectra electrochemical behavior was characterized
