【Abstract】 Progress of application of heterocyclicazo reagents in precious metal ions analysis at home and abroad from 1996 to present was summarized systematically, including spectrophotometry, high performance liquid chromatography, polarograph,laser thermal lens spectrometry and other instrumental analytical methods. Some developmental perspectives in this research field were prospected. New fast and sensitive analytical systems of precious metal ions would be established on the basis of the combination of the excellent chromogenic characters of heterocyclicazo reagents with new kinds of instrumental analytical methods. 123 references were cited.更多还原
