摘要
本文主要报导最近12年(1977—1988)中分光光度测定亚硝酸根的方法的现状与进展。文中综合了51篇文献中报导的37种方法,并用表列出每种方法的显色介质、最大吸收波长、适宜浓度范围及分析对象。
Methods for the spectrophotometric determination of nitrite dur-ing the years of 1977 to 1988 have been reviewed. The review includes37 methods and 51 references. Optimum conditions for the developmentof colouration, wavelength of maximum absorption, Beer's law foroptimal concentration range as well as applications of the methodsare listed in tables for each method.
