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.
