Chitosan-graft-poly (acrylonitrile-co-acrylic acid) to treatment the waste water

Azza Mahmoud Mazrouaa

Chitosan is a biodegradable natural based polymer obtained from chitin (N-deacetylated derivative), the second most abundant polysaccharide after cellulose and soluble in most organic acids. Graft copolymerization of poly (acrylonitrile-co-acrylic acid) onto chitosan has been successfully carried out using potassium per sulfate as initiator in an aqueous medium.
