Radioactive liquid waste contains significant quantities of platinum group metals such as palladium (Pd), rhodium (Rh) and ruthenium (Ru). There are many techniques, such as solvent extraction, precipitation, ion exchange, and adsorption methods, for the separation and recovery of Rh. In this study, batch and column experiments were carried out to investigate the ion exchange and elution characteristics of Rh from a simulated radioactive liquid waste by commercial cation and anion exchange resins such as Dowex 50W, IRN 78 and Dowex 1×8. The effects of the ionic group of resins, the solution temperature, and the concentration of nitric acid were investigated. Also, the elution characteristics of Rh by various eluents were studied.

Keywords:rhodium;ion exchange;resin;adsorption;elution
