Synthesis of Cationic Starch Flocculant and Properties

Abstract:

Based on the high turbidity feature of mine water, Glutinous Rice Starch(St)- Acrylamide(AM) graft polymer cationic flocculant was synthesised by copolymerization with St and AM as materials, ammonium persulfate and sodium hydrogen sulfite as the initiator, 2.3-glycigyl trimethyl ammonium chloride were used as cationic agent. The optimum condition of cation was established through orthogonal experiments: reaction time is 4 hrs, St dosage is 5g, mass ratio of AM and St is 4:1, dosage of initiator is 1.4g, GTA dosage is 2.6g, NaOH dosage is 0.24g, etherification reaction time is 2.5 hrs, reaction temperature is 70°C. The performance of the cationic starch flocculant used as the mine wastewater treating was evaluated.
