FIELD: chemical technology. SUBSTANCE: solution containing Rh, Ir and Ru is contacted with sorbent that is unbranched or branched macrocyclic or nonmacrocyclic polyalkylene-polyamine-containing ligand bound covalently with solid inorganic backing. The general formula of sorbent: matrix-O-
-X-ligand. Metal complex with sorbent is separated from solution and metals were desorbed for two stages. Firstly, Rh and/or Ru were extracted by treatment with the first collecting solution taken at volume less than the parent solution volume. Then Ir is extracted by treatment with the second collecting solution at volume less than the parent solution volume. Method is used for extraction, separation and concentration of Rh, Ir and Ru from solutions. EFFECT: high effectiveness and economy of method, accelerated process. 12 cl
