前言离子选择性电极作为一种新的分析测量手段,近年来在国内外都得到了广泛、迅速的发展,硝酸根电极就是其中的一种。关于硝酸根电极的研制及其应用情况,国外的报导很多,并有商品电极出售。该电极在土壤、水质、植物,微生物、炸药及工艺流程的分析中都获得广泛的应用。此外,也可用于络合物的研究。目前比较成熟的硝酸根电极主要是液态离子交换型的电极,所采用的交换剂基本上可分为两类:一是含长脂肪链的季铵盐(例如Corning
Introduction Ion selective electrode as a new analytical measurement means, in recent years at home and abroad have been extensive and rapid development of nitrate electrode is one of them. About nitrate electrode development and its application, many foreign reports, and the sale of goods electrodes. The electrode in the soil, water quality, plants, microorganisms, explosives and process analysis have been widely used. In addition, it can be used for the study of complex. Currently more mature nitrate electrode is mainly a liquid ion exchange type electrode, the exchangers used can basically be divided into two categories: First, with a long chain fatty acid quaternary ammonium salt (such as Corning
