Synthesis and properties of polyfunctional anion exchangers based on aniline and some polyamines

In this article, the authors present the results of the synthesis of ion-exchange materials based on various nitrogen and oxygen-containing compounds and some polyamines, the study of sorption properties, obtaining ion-exchange sorbents based on them, as well as finding the most promising areas of their application.In the present work, ionites based on polyethylene polyamine and diglycidylaniline, as well as polyethyleneimine and diglycidylaniline were synthesized.The sorption properties of ion exchangers on copper cations were studied.The practical significance of the work is that in their sorption properties they are 2-4 times higher than the industrial anion exchangers of macroporous and gel structures, which contribute to better wastewater treatment.The study of the sorption properties of ionites on copper cations showed that they are 2-4 times higher than the industrial anion exchangers of macroporous and gel structures.
