FIELD: materials for separation.
SUBSTANCE: disclosed is a method of producing a polydentate functional monomer of the N,O-type through a Michael's addition reaction between N-aminoethyl-γ-aminopropyltrimethoxysilane and an acrylic acid-based compound, wherein the ester groups are bonded to amino groups and imino groups of N-aminoethyl-γ-aminopropyltrimethoxysilane, the ester groups are then hydrolysed using a trifluoroacetic acid solution. Two nitrogen atoms and three oxygen atoms in the functional monomer can be coordinated with metal ions. Polydentate functional monomer of N,O-type, obtained in accordance with the present invention, can be used to produce material with ion imprint, which is characterized by high selective adsorption capacity with respect to copper ions and nickel ions. Proposed method for synthesis of Cu2+-IIP based on AAPTS-COOH has high versatility and can be used for imprinting of ions of other metals, simultaneous imprinting of ions of several metals and imprinting of organic molecules.
EFFECT: obtaining a polymer with an ionic imprint with improved selectivity with respect to metal ions.
