离子选择电极是一种近年来新发展起来的电化学分析工具。它的最大特点是快速、简便,测量范围宽,不受溶液颜色、浊度的影响,易于实现自动分析和流线分析。本文介绍我们在实验室使用中遇到的一些具体问题。参比电极的选择和使用众所周知,、单独的离子选择电极的膜电位不能直接测量,必须构成自发电池。一般情况 Ion-selective electrode is a newly developed electrochemical analysis tool in recent years. Its greatest feature is fast, easy, wide measuring range, free from the influence of solution color and turbidity, easy to realize automatic analysis and streamline analysis. This article describes some of the specific problems we encountered in the lab. Selection and Use of Reference Electrodes It is well known that the membrane potential of an individual ion-selective electrode can not be measured directly and must constitute a spontaneous cell. generally
