FIELD: methods for separation of metal ions. SUBSTANCE: method involves applying phosphorus-organic extragent (trioctylphosphinoxide, tributylphosphate) to polymeric carrier (polytetrafluorethylene, polystyrene, polychrome). Solutions of ions being separated, e.g. fragmentary radionuclides are treated with trichloro- or trifluoroacetic acid or with their sodium salts. Prepared solutions are applied to a column with extragent. Eluation is carried out with aqueous solutions containing trifluoro- or trichloroacetate ions. EFFECT: higher efficiency. 2 dwg
