Abstract: Synthetic polymeric sorbents are characterized by high physical and chemical stability and heat resistance; they are relatively inert and hydrophobic which makes them highly sought in water treatment and hydrometallurgy. However, this substance is costly. Therefore, it is necessary to develop the main stages of industrial synthesis of high-capacity low-basic anion exchangers based on acrylonitrile which is the purpose of this study. The study investigates the synthesis and properties of anion exchangers based on acrylonitrile for use in water treatment and the conditions of the copolymerization reaction which increases the yield and quality of the conditioned copolymer. Samples of anion exchangers with high capacity and osmotic stability characteristics were obtained by aminolysis of nitrile groups in the synthesized copolymers. The study developed regimes of anion exchangers with better quality characteristics than those of similar sorbents.
