近年来,离子选择性电极这一新的分析测量工具正日益受到人们的重视,并且已在各个领域中发挥着越来越大的作用。如所周知,离子选择性电极是一类对溶液中的离子有选择性响应的指示电极,当电极插入含有某种能产生电极响应的离子的溶液中时,由于离子交换等响应机理而在电极表面产生一个膜电势,它的大小与溶液中该离子的活度间存在着简单的能斯脱 In recent years, ion-selective electrode, a new analytical measurement tool, is gaining more and more attention and has been playing an increasingly important role in various fields. As is known, ion selective electrodes are a type of indicator electrode that responds selectively to ions in a solution. When an electrode is inserted into a solution containing some ion that produces an electrode response, due to the response mechanism such as ion exchange, Surface produces a membrane potential, its size and the activity of the ions in the solution there is a simple Nesteth off
