| Abstract: | In an ethanol-water system,starch-modified AM-DMDAAC cationic flocculant was prepared.The monomer mass ratio,mass ratio of starch and monomer,initiator dosage and type of initiator on the polymer performance were studied.The results show that the optimal conditions are that the mass ratio of AM（acrylamide） and diallyl dimethyl ammonium chloride is 5∶1,the ration of AM and starch is 2∶1,and the mass fraction of initiator,potassium persulfate and ammonium cerium nitrate is 0.04%.The product has a good flocculation performance. |
