离子选择电极是20世纪60年代中期以后迅速发展起来的一种新型的分析工具。选择电极测量技术具有灵敏度高,设备简单,操作方便,能连续,快速,自动地进行测量等一系列优点。因此,在国际上已被广泛地应用于地质、冶金、化工、海洋、土壤、医学和环境保护等各个领域,成为一种有效的测试手段。 Ion-selective electrode is a new analytical tool developed rapidly after the mid-1960s. Select electrode measurement technology with high sensitivity, simple equipment, easy operation, continuous, rapid, automatic measurement and a series of advantages. Therefore, it has been widely used in various fields such as geology, metallurgy, chemical industry, marine, soil, medicine and environmental protection in the world and has become an effective test method.
