摘要
本文介绍最近三年来铌和钽的分光光度及荧光光度分析的进展情况并提供70篇文献供参阅。
In present paper, the recent development of Spectrophotometric and fluorimetric analysis of nio-bium and tantalum is described.Various coloring reagents and systems of niobium and tantalum involving trihydroxyfluorories, pyridylazo or thiazoiylazo series, pyrogallol rot series, assaciated substances of heteropoly acid of niobium ( v ) or tantalum ( v ) witii basic dyesi extractive and other spectrophotometry have been. introduced. The fluorimetry and phosphorimetry are also reviewed. It includes 70 references.
