METHOD OF PRODUCING SORBENTS BASED ON MEDIA AND CROWN ETHERS AND 1,1,7-TRIHYDRODODECAFLUOROHEPTANOL-1 AS DILUENT Russian patent published in 2017 - IPC B01J20/32 B01J20/22

Abstract RU 2636482 C1

FIELD: chemistry.

SUBSTANCE: method of producing a sorbent includes preparing the medium, treating it with heating and stirring with a solution of crown ether in an organic solvent. As a diluent, 1,1,7-trihydrododecafluoroheptanol-1 is used. Subsequently, the solvent is distilled off at its boiling point and the sorbent is dried to constant weight.

EFFECT: decreasing the washing out of the crown ether from the sorption system to produce high distribution coefficients in the recovery of metal ions.
