FIELD: chemistry.
SUBSTANCE: invention relates to a sorbent that is suitable for binding metals from solutions, to the production the corresponding sorbent, as well as to the use of a sorbent for binding metals from solutions. Sorbent contains a porous substrate material coated with a polymer containing an amino group. Concentration of amino groups of the sorbent, determined by titration, is at least 600 mcmol/ml relative to the total volume of the sorbent. Polymer containing the amino group is present in a non-covalently bound form with a porous substrate material. Pore volume of the porous substrate material ranges from 30 to 90 vol% relative to the total volume of the porous substrate material. Porous substrate material has an average pore size from 6 nm to 400 nm.
EFFECT: invention provides a sorbent with high binding capacity.
