Аннотация: The sorption preconcentration of Pd (II) and Pt (IV) from hydrochloric acid solutions on Purolite ion exchangers with different functional groups was investigated. The initial concentrations in contacting solutions were 0.025-0.25 mmol/L for palladium and 0.25 mmol/L for platinum at the HCl concentrations 0.01-4.0 mol/L. It was shoПоказать полностьюwn that the investigated resins have high sorption ability (more than 85-95 %) to chloride complexes of noble metals. We found out that the simultaneous elution of these complexes by hydrochloric acid thiourea solution (1 mol/L in 0.5 M HCl) is possible (to more than 80 %) from anion exchangers Purolite A 111 and Purogold(TM) A 193.
