铑铱分离方法与原理

本文将文献报道的和生产使用的铑铱分离方法按原理的，利用金属特性的差异，利用ＲｈＣｌ＾３－６与ＩｒＣｌ＾３－６配离子稳定性的差异，利用ＲｈＣｌ＾３－６与ＩｒＣｌ＾２－６负电荷数的差异以及将Ｒｈ（Ⅲ）配阴离子转化为阳离子等四类。每类中又按沉淀法，还原法，萃取法和离子交换法分别进行介绍，并按作者的理论观点给予简要说明。

The Method and Principle for Separation of Rhodium and lridium

This paper deals with the classification of methods used for separa-tion of rhodium and iridium according to the principles.On the basis of the differences either in both metals or in their complexes,the methods are divided into four categories.Each category is introduced in terms of preci-pitation,reduction,solvent extraction and ion-exchange. Theoretical dis-cussion is also given in the paper.
