摘　　要：对铂族金属氯络合物的吸收光特性做了研究。实验表明它们均有各自的吸收峰和谷，利用这一特性可应用于贵金属合金的定量分析而不需进行分离。对络合物的形成条件、线性范围及实际应用做了研究和讨论。以测定铂铱合金中铱为例阐明了分析方法原理和实验步骤。铱含量为１０％时标准偏差（９）为０．１５％。he light absorption characteristics of chromium complex formed by platinum family metal and chlo-ride has been studied. The Experiment shows that they have their own absorptive peaks and vallys respec-tively. These characteristics can be used for the quantitative analysis of noble metal alloys,and no need to separate them. The handling sequences are very simple. The author has studied the forming conditions,linear range and actual application of chromium complex.And this article also demonstrates the analysis methods,principles and the experimental procedures by measuring the iridium in the platinum and iridium alloy as an example. The standard deviation is 0.15%when the iridium content is 10%.
