Abstract
ABSTRACTIn the search for new polymeric supports for the synthesis of ion-exchange resins, a new method has been assessed. A series of core-shell-type polymeric supports, based on the Amberlite XAD-4 adsorbent and vinylbenzyl chloride-divinylbenzene copolymer, has been obtained. The polymers, characterized by a diversified porous structure, were assessed by their functionalization into anion exchangers and their ability to remove Au(III), Pt(IV) and Pd(II).The efficiency of functionalization using ethylenediamine, as well as sorption capacity, was compared to the textural parameters of the initial supports, defining methods and techniques that will allow materials characterized by the most efficient usage of the vinylbenzyl chloride (VBC) monomer to be obtained.
