Output (English): The selective sorbent for the separation of the ions of these metals from the polymeric carrier to which the sorbic complexing agent is based on the organic organic matter, where the polymeric carrier contains a basic active center of the pyridine type or the second type, the third one. or quaternary amine groups. The complex n is selected from the group consisting of dialkyl phosphorous, dialkyl thiophosphorous or dialkyl dithiophosphoric acids of the general formula (RO). carbon alkyl with 4 and 18 carbon atoms and X is an acid to or with. A method of preparing a selective sorbent based on an organic acidic agent on a support which is contacted by the polymeric support is transferred to a basic form with a weight of 5% and a 15% solution of the complexing agent in the inert form. organic solvent based on water. \ t
