摘要： 铑-铱分离-向被认为是最困难的课题之一[1.2],即使文献[3～6]曾报道Rh-Ir的分离,但实际Rh并未与萃取剂或吸附剂反应,而是与非贵金属离子一同留在溶液中。我们曾用光谱半定量方法研究了AP树脂对Rh、Ir的吸附行为,结果是Rh不被吸附而Ir能被吸附。本文通过改变Rh的离子状态,使之能被AP树脂吸附完全,而与留在溶液中的非贵金属分离,然后在柱上用不同淋洗液再使Rh-Ir分离。

Abstract: Separation of Rh-Ir which has not been completely dissolved is one of the most difficf.lt problem in analytical chemistry. In this paper, we have found the favourable conditions under which base metals-Rh-Ir can be better separated on APchelate resin and the appropriate eluant for simultaneous elution of Rh-Ir-Pt-Pd followed by ICP-AES. It must be mentioned that only the ion form of [RhCl5 (H2O)]2- can be retained on the APresin column and separated from base metals in the solution.
