摘要
本文详细评述了变色酸双偶氮类试剂在测定非稀土元素方面的最近进展,着重讨论此类试剂在光度分析中的应用.引用文献117篇.
In this paper, the recent advances of the determination of non-rare earth elements with un-晄ymmetric bis-arylazo derivatives of chromotropic acid were reviewed in detail. The applications of spec-trophotometry were described emphatically. A total of 117 references -were cited.
