SYNTHESIS AND CHARACTERIZATION OF GRANULAR ION EXCHANGERS BASED ON ACRYLONITRILE COPOLYMERS

This work presents the results of synthesis granular copolymers acrylonitrile with hexahydro-1,3,5-triacrylyltriazine and their modification organic amines, in particular diethylamine, as well a study physicochemical characteristics sorption properties obtained ion exchangers. The result was exchangers necessary based on divinylbenzene, N,N´-methylene-bis-acrylamide hexahydro-1,3,5-triacrylyltriazine, kinetics this process studied. synthesized were modified ion-exchange polymers It has been shown that acrylonitrile, its coated them, can be obtained. For first time, and, basis, conditions for obtaining weak anion-exchange resins complex basis developed. anion have complexing used hydrometallurgy non-ferrous heavy metals, purification waste water from toxic ions, separation concentration metal ions.
