Аннотация: The sorption pre-concentration of platinum(II,IV) ions was investigated in presence of accompanying copper(II) and zinc(II) ions from chloride solutions on new previously unexplored ion exchangers (Cybber, Russia). The initial concentrations of platinum and the accompanying ions were 0.25 and 2.0 mmol L-1, respectively, and the acidity of medium was 0.001-4.0 mol L-1 HCl. It was shown that the investigated resins - strong and weak basic anion exchangers as well as chelate ion exchangers - possessed good sorption and kinetic properties. The simultaneous sorption of the investigated ions results in the complete recovery of platinum, while the non-ferrous metal ions were sorbed at less than 20 %. Followed by the selective elution of platinum by a thiourea (80 g L-1) solution in 0.3 M H2SO4, the quantitative isolation of platinum was achieved (more than 90 %). Therefore, the studied ion exchangers could be recommended for the recovery and separation of Pt(II, IV), Cu(II) and Zn(II) ions.
