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.

Key words: Separation of Rh-Ir, Simultaneous determination of Rh-Ir-Pt-Pd, a- Amino pyridine AP chelatc resin
