Abstract

The graft copolymerization of acrylonitrile (AN) onto the bleached dissolving pulp (yield from corn husks) under the initiation of potassium persulfate (KPS) was investigated. The relationships between the grafting efficiency percent and KPS concentration, monomer to pulp ratio, reaction time, as well as reaction temperature were established. The grafted cellulose has been characterized by FTIR and swelling studies. Sorption of Ni ions by grafted cellulose was investigated. The effect of Amidoximation of the grafted cellulose using hydroxylamine to convert nitrile group to amidoxime then its swelling properties and metal ion sorption were investigated. Amidoximation increases the sorption affinity of the grafted cellulose towards water and metal ions.
