Synthesis and Performance-Characteristics of Methylmethacrylate-Divinylbenzene Copolymer-Based Chelating Resin for Gallium Metal Recovery
A chelating ion exchange resin based on a methylmethacrylate and divinylbenzene copolymer has been designed through suspension polymerisation and subsequent functionalisation to hydroxamic acid as chelating group. The chelating resin has been characterized by infrared spectroscopy, its particle size, stability in acid/alkaline media, specific gravity and its use in gallium recovery. The use of resin has been demonstrated to effect gallium recovery with an efficiency of about 80%.
