A novel chelating resin with diphenyl disulphide functional group: Synthesis, sorption, separation and recovery of some heavy metal ions

Abstract

A novel chelating resin containing diphenyl disulphide as a functional group, supported on poly-(ethylacrylate-acrylonitrile-divinylbenzene) was synthesized by suspension polymerization and characterized by elemental analysis, physico-chemical properties thermal studies, FTIR studies and scanning electron microscopy. With the help of batch equilibrium technique, the selectivity and binding capacities of chelating resin were measured towards certain metal ions in different electrolyte concentration, wide pH range and different time intervals. The maximum adsorption capacities of the resin for Co (II),
