摘要
本文介绍一种控制电流的四电极伏安仪。仪器具有电流环扫伏安法、滴水极谱法、恒流计时电位法及反向计时电位法四种功能。四甲基铵阳离子在水/1,2-二氯乙烷界面上的传输研究表明,仪器性能稳定,可用于两互不溶电解质液界面的电化学研究。
A voltammetric instrument at controlled current with afour-electrode arragement and an electrolytic cell with a four-electrode con-figuration forinvestigation of electrochemistry at the interface betweentwo immiscible electrolyte solutions(ITIES)have been developed.The in-strument is composed of following parts:(1)a current controller;(2)a monitor of the potential difference between two phase;(3)a compens-ator for ohm drop between two reference electrodes;(4)a recorder of vo-ltammetric curve.Its four functions are examined by the studies on tra-nsfer of TMA^+(tetrametrylammonium ion)across an aqueous 1,2-dichl-oroethane interface.The result indicates that the instrument has steadyproperties and can be used in the investigation of electrochemistry atITIES.
