This article reviews the development in ion amperometry at the interface between two immiscible electrolyte solutions (ITIES) in view of realizing the amperometric ion-selective electrode (ISE). The concept of polarizability of ITIES in a multi-ion system is outlined. Principle aspects of ion amperometry at ITIES are discussed including the use of amperometry as a tool for the clarification of the ion sensing mechanism, and for determining the concentrations of ions in the solution. The reference is made to recent amperometric measurements at the supported liquid membrane (SLM) and polymer composite liquid membranes (PCLM), which, together with the micro-hole supported ITIES, appear to be particularly suitable for realization of the amperometric ISE.
本文从实现电流型离子选择性电极(ISE)的角度,综述了两种不混溶电解质溶液(ITIES)界面处离子电流分析法的发展。概述了多离子体系中ITIES的极化率概念。讨论了ITIES处离子电流分析法的主要原理,包括将电流分析法用作阐明离子传感机制以及测定溶液中离子浓度的工具。文中还提及了近期在支撑液膜(SLM)和聚合物复合液膜(PCLM)上进行的电流测定,它们与微孔支撑的ITIES一起,似乎特别适合于实现电流型ISE。
