摘    要:应用传统的三电极体系在微孔电极尖端支撑的液/液界面上,采用循环伏安法、计时电流法、方波伏安法研究了互不相溶电解质界面(1TIES)上铁氰化钾/亚铁氰化钾(水相)和二茂铁(有机相)的电子转移反应,计算得到反应中二茂铁在有机相中的扩散系数.实验证明该方法操作简便易行,是研究液/液界面上电子转移反应的有效工具.

关 键 词:液/液界面  电子转移反应  微孔电极  扩散系数  二茂铁  电荷转移反应  循环伏安法

Abstract:The electron transfer between potassium ferricyanide, potassium ferrocyanide (water phase) and ferrocene (oil phase) across two immiscible electrolyte solutions (ITIES) supported with micro-cavity electrode has been investigated with cyclic voltammetry, chronoamperometry and square wave voltammetry by a traditional three-electrodes system. The diffusion coefficient was derived from the data. The results showed that the ITIES supported by micro-cavity electrode would be a useful and efficient tool to investigate the charge transfer reactions at liquid/liquid interfaces.
Keywords:micro-cavity electrode  liquid/liquid interfaces  electron transfer
