Abstract
The investigation is devoted to sorption recovery of platinum (II, IV) from chloride solutions, freshly prepared and kept over 3 months, on commercial anion exchangers with different physical and chemical structure. The resins were chosen for their good sorption properties for other noble metal systems (gold, silver and palladium) in our previous investigations. The concentration of platinum in initial solutions was 0.25–1.0 mmol/L, whereas hydrochloric acid concentration varied from 0.01 to 4 mol/L. It was shown that anion exchangers investigated possess high sorption ability to chloride complexes of platinum (II, IV). These sorption characteristics do not deteriorate in case of noble metals recovery from kept solutions.
