A new anion exchanger was synthesized by the reaction of granulated polyvinyl chloride (PVC) with polyethylene polyamine. The physicochemical parameters of the sorbent were determined. Anion-exchange properties of the newly synthesized ion exchanger were studied by the sorption of Cr(VI) ions. It was found that it does not lose its sorption properties even at tenfold use in the test of the sorbent in technological conditions.
Взаимодействием гранулированного поливинилхлорида с полиэтиленполиамином синтезирован новый анионит. Определены его физико-химические параметры. На примере сорбции ионов Cr(VI) изучены анионообменные свойства полученного ионита. При испытании данного сорбента в технологических условиях было установлено, что он не теряет своих сорбционных свойств при десятикратном использовании.
