FIELD: nonferrous metallurgy, in particular, affinage of platinum metals. SUBSTANCE: method involves providing oxidizing treatment of chloride platinum-palladium solution with sodium chlorate solution at temperature of 70-90 C. Method allows contaminant content in final palladium salt to be reduced. EFFECT: reduced labor intensity for reaffinage of palladium salt and decreased irreversible palladium losses with refined palladium. 2 tbl, 12 ex
