Synthesis of Polyamidoxime Chelating Ligand from Polymer-Grafted Corn-Cob Cellulose for Metal Extraction

A conventional free-radical initiating process was used to prepare graft copolymers from acrylonitrile (AN) with corn-cob cellulose with ceric ammonium nitrate (CAN) as an initiator. The optimum grafting was achieved with corn-cob cellulose (anhydroglucose unit, AGU), mineral acid (H2SO4), CAN, and...
