Abstract


This experiment is a continuation of our effort to develop a blend membrane of sodium alginate and “konkoli” gum-g-polyacrylamide (KG-g-PAAm) for bioremediation of wastewater. The effect of graft reaction conditions on the percentage graft yield in the graft copolymerization was investigated. It was observed that grafting parameters such as acrylamide (AM), ceric ammonium nitrate (CAN), “konkoli” gum (KG), temperature and reaction time have remarkable influence on the percentage graft yield of the
graft copolymer. The percentage graft yield initially increased and then decreased for all the parameters investigated. Optimum percentage graft yield of 83, 85, 86, 84 and 84 were obtained by varying AM,
CAN, temperature, reaction time and KG, respectively. This result present the optimum grafting conditions required for copolymerization of AM onto KG.
