摘要： 贵金属混合物光度分析常需分离,同时测定的报导亦少见。本文提出了一种不用分离,不用萃取,不用解联立方程,灵敏、简便同时分光光度测定三种贵金属的方法。

Abstract: Asimple, accurate, sensitive, and reliable . method for simultaneous spectrophotometrie determination of palladium, platinum and rhodium in the their mixtures has been suggested. The method involves first, in the medium of EDTA-NaOHthe determination of palladium as the red PARcomplex without interference from platinum, rhodium and many foreign cations. Then, by the use of the perchloric acid and stannous bromide, both the excess PARand its palladium complex were decolorized.
