SYNTHESIS AND STUDY OF ANIONITE BASED ON DOUBLE COPOLYMER OF GLYCIDYL METHACRYLATE, ACRYLONITRILE AND POLYETHYLENIMINE

Abstract

The article discusses a method for obtaining a new anionite by amination of a double copolymer of glycidyl methacrylate and acrylonitrile with polyethyleneimine. Its physical and chemical properties have been studied. The optimal synthesis conditions were determined, the composition and structure of the anionite were studied by IR spectroscopy and elemental analysis. Anion exchanger based on glycidyl methacrylate copolymer (GMA-ACN) is promising in hydrometallurgy processes. Ion exchange processes associated with the separation, isolation and purification of complex molecules of organic and inorganic compounds require the creation of ion exchange materials capable of absorbing large ions and molecules. This, in turn, arouses interest in the development of effective methods for the production of such sorbents and the study of their properties, research, providing for the improvement of production technology and expansion of their range.
