Abstract
Abstract Magnetic anion exchange resin (MD-1) was prepared from quaternization of magnetic copolymeric resin (glycidyl methacrylate-co-divinylbenzene). For comparison, magnetic resin MD-0 without quaternization and non-magnetic resin (D-1) were also synthesized for the adsorption process. It was found that the adsorption was mainly contributed to the chemical interaction between quaternary ammonium groups and reactive blue RXHC. Due to the smaller size, MD-1 had faster adsorption and desorption kinetics than D-1. Coupled with the advantage of easy separation, the magnetic anion exchange resin was considered to be superior to common anion exchange resin in removal of reactive dye.
