Preparation and adsorption performance of polyacryloyloxytrimethylammonium chloride-modified magnetic chitosan microspheres: a novel strategy for treating Cr(vi) ion-containing wastewater

Novel highly efficient and reusable magnetic chitosan microspheres (PMCPs) were fabricated by grafting polyacryloyloxytrimethylammonium chloride, which provided a new strategy for the treatment of Cr( vi )-containing wastewaters.
