Partial separation of rhodium and iridium using polyurethane foam

Rhodium/III/solutions react with tin/II/chloride to form a short-lived yellow complex which is extracted by polyurethane foam. Iridium/IV/solutions are decolourised by thin/II/chloride, but the metal is poorly extracted by foam. The Rh/III/complex is readily desorbed from foam using hydrochloric aci...

Description
Summary:Rhodium/III/solutions react with tin/II/chloride to form a short-lived yellow complex which is extracted by polyurethane foam. Iridium/IV/solutions are decolourised by thin/II/chloride, but the metal is poorly extracted by foam. The Rh/III/complex is readily desorbed from foam using hydrochloric acid and acetone. 7 ref.--AA
