Аннотация: The sorption concentration of platinum(II, IV) in the presence of iron(III) is studied on new samples of domestically produced ionites of the CYBBER brand. In comparing the sorption and kinetic properties of the new ionites to those of sorbents of the Purolite brand studied earlier, the higher effectiveness of the former is demonstПоказать полностьюrated via the extraction of platinum(II, IV) ions from strongly and weakly acidic chloride solutions. It is found that the sorbed platinum ions can be completely separated from iron(III) ions through separate elution using 0.01-0.001. HCl (iron ions) and a thiourea solution (80 g/L) in 0.3. H2SO4 (platinum ions).
