摘要
参考了35篇文献,总结了变色酸双偶氮试剂与非稀土金属离子的β型反应,研究了试剂结构、介质及酸度、有机溶剂及表面活性剂、显色时间及显色体积、显色温度对β型反应的影响.
A review is presented on the recent advances of the β-chromogenic reaction of diazo compounds of chromotropic acid with metal ions besides rare earth elements. Emphases are given especially on the effects of the molecular structure of the reagents and the optimun conditions for the 3 type reaction (with 35 references).
