GRANULES OF MOLECULARLY IMPRINTED POLYMERS FOR METAL EXTRACTION AND USE THEREOF Russian patent published in 2020 - IPC B01J20/26 B01J20/28 C22B3/24 B01D15/04 B01D15/34 B01D15/36 B01D15/38 

FIELD: chemistry.

SUBSTANCE: invention relates to molecularly imprinted polymers. Described is a plurality of macroporous polymer granules for selectively binding one or more metal target ions containing a copolymer, having a plurality of complexing cavities which selectively bind a metal ion target, where the copolymer is obtained from: (a) a ligand monomer which is cationic or anionic and is in complex with a substitute non-metallic ion, (b) a non-ligand monomer and (c) a cross-linking monomer, where (i) the charge in the complexing cavity of the copolymer is opposite to the charge of the metal target ion and (ii) the substitute non-metallic ion has substantially a shape and a charge similar to the metal target ion. Invention also describes a method of producing granules of a macroporous molecularly imprinted polymer, a method for selective extraction of one or more target metal ions from a solution.

EFFECT: improved operational characteristics when producing macroporous polymer.
