| Abstract: | Poly(vinyldiethylenetriamine) chelating resin was synthesized from macroporous poly(vinyl chloride) and used for the enrichment-separation of rhodium and iridium. The efficiency, rate and equilibrium constant adsorption of rhodium and iridium on the resin were determined and real samples were analysed. The mechanism of rhodium and iridium enrichment is discussed. |
