Grafting co-polymerization of chitosan and acrylamide with inexpensive ammonium persulfate as initiator was studied and the property of flocculating of the co-polymerization product was also studied.Experimental results show that the grafting percentage is 133.40%, viscosity is highter than 100 000 mPa·s trans-mittance of treating simulated waste water is 99% and the property of flocculating is the best when the concentration of initiator is 3 mmol/L, the mass ratio of chitosan to acrylamide is 2:1, reaction temperature is 30℃, reaction time is 3~3.5 h and the volume fraction of glacial acetic acid is 1.5%.
