钒的光度定量方法所选用的显色剂,大都是有机试剂。近年来有机显色剂发展很快,名目繁多、应用很广,其中重要的有:偶氨化合物、含羟基类化合物、羟胺衍生物、苯胺化合物等。另外还有利用钒对一些有机试剂的显色反应具有催化作用,而用以进行催化光度测定。本文就钒的光度方法中重要有机试剂的发展情况作一归纳和讨论。 Vanadium photometric method of choice for the developer, mostly organic reagents. In recent years, the development of organic developers quickly, a wide range of projects, a wide range of applications, including the important: even ammonia compounds, hydroxyl-containing compounds, hydroxylamine derivatives, aniline compounds. In addition there is the use of vanadium for some organic reagents have a catalytic chromogenic reaction, and for catalytic spectrophotometry. This article summarizes and discusses the development of important organic reagents in the vanadium photometric method.
