Preparation and properties of epoxided Separon-based ion exchangers with bonded 8-hydroxyquinoline

Abstract

The direct fixation of copper(II) 5-(4-hydroxyphenylazo)-8-quinolinate and the indirect fixation of 8-hydroxyquinoline to Separon H 40E_max and Separon H 1000 E_max were compared from the point of view of the practical sorption capacities of the resulting ion exchangers. For the ion exchanger obtained by indirect fixation of the reagent to Separon H 40 E_max, the rate of Cu²⁺ ions, and the stability were determined and compared with those of a G-gel-based ion exchanger.
