摘要 The title copolymer was synthesized by grafting dimethyldiallylammonium chloride onto chitosan with ammonium cerium nitrate as initiator. The effects of reaction temperature, pH and concentration of initiator on product yield were examined. The optimum conditions were as follows:90 ℃, concentration of initiator 5×10 -4 mol/L, pH=6. The flocculation experiments on the fermentation wastewater showed that flocculabi- lity of the chitosan graft copolymer was better than the chitosan itself and the flocculation treatment could be carried out at lower dosage and wider pH range.
