摘要: 本文研究了一种适用于液/液界面电化学研究的悬液电解池及其性能,它能产生3~20mm2的球形界面和0.025mm2的微盘界面。通过微量注射器调节,界面易更新,且液滴稳定时间长达1h。介绍了一种耐强极性有机溶剂接触的玻璃表面疏水处理方法,经处理后的电解池可连续使用14天。以典型的四乙基铵离子的转移特征来验证本电解池的性能,获得满意的结果。

Abstract: A new hanging aqueous drop electrolytic cell has been constructed which could provide a microdisc(0025 mm2) or a spherical(3~20 mm2) liquid/liquid interfaceThe drops could be renewed easily by a microsyringe and stabilized for about 1 hThe voltammetric results of the te-traethylammonium ionic transfer across the water/1,2-dichloroethane interface show the cell is suitable for the electrochemical studies at liquid/liquid interface.

Key words: Electrolytic cell, Hanging drop, Liquid/liquid interface
