Ion exchange experiments have been done to separate Pt(IV) and Rh(III) from chloride solution. Loading of the two metals into anion exchange resins, such as AG1-x2, AG1-x8 and AGMP-1 resin, was investigated in the HCl concentration range from 0.1 to 5 M. The concentration ratio of Pt and Rh in the chloride solution was fixed at 10:1. It was found that the loading of Pt into the resins followed Langmuir isotherm. The resins employed in this study had selectivity for Pt over Rh. The concentration of HCl had a pronounced effect on the loading of the two metals and Pt was effectively separated from Rh at low concentration of HCl. Batch experiments indicated that AG1-x8 resin was the most effective in separating Pt and Rh in our range. Continuous experiments with AG1-x8 resin verified that complete separation of Pt from Rh was possible. The loaded AG1-x8 resin was successfully regenerated by elution with thiourea.
