PRODUCTION OF ANIONITE BY MODIFICATION OF POLYVINYL CHLORIDE IN THE PARTICIPATION OF UREA

Аннотация

In recent years, ion-exchange materials based on synthetic polymers have been used in the mining industry for the selective extraction of non-ferrous, rare, heavy and rare metals, as well as in the concentration of technological solutions, in the desalination of river waters for the use of atomic and thermal energy, as well as in chemical industries. In softening, a widely used, economically cheap and effective method of wastewater treatment is the ionization method with the presence of ions [1]. Therefore, the synthesis of new ion exchange materials based on local raw materials and the study of their important properties are urgent issues. Due to their high operational properties, ion exchange materials are widely used in almost all fields of science and industrial practice. With their help, one of the most urgent social and environmental problems is being solved: environmental protection. [2;3]. In particular, it has a high sorption property against various metals, is chemically stable, is stable to temperature changes, and is cheap. must meet the requirements [4]. The method of separation of existing ions in water with the presence of ionites meets exactly such requirements [5]. Therefore, synthesis of new ionites with high sorption properties is of great practical importance.
