The article studies the properties of obtaining anionite based on a triple copolymer of
glycidylmethacrylate, styrene and Acrylonitrile and its suction of strontium ions. The composition and structure of
the obtained anion was determined by infrared spectroscopy, were also studied basic physicochemical properties of
the resulting anion.
Anionite, presented on the basis of GMA-ST-ACN, is promising in the field of ion exchange process and is used
for the extraction of strontium ions from aqueous solutions in the field of hydrometallurgy.
The work is devoted to a review of the preparation of cross-linked polyelectrolytes, the extraction of strontium
(II) ions using anionites. The possibilities of obtaining new nitrogen-containing anion exchangers based on a
copolymer of glycidyl methacrylate (GMA), styrene (St) and acrylonitrile (ACN) have been studied. The optimal
synthesis conditions were found and the physicochemical properties of the ion exchanger were investigated. Methods
for the preparation of new anionites based on a copolymer of glycidyl methacrylate (GMA) with polyethylene
polyimines (PEI) have been developed.
