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.
Starch modified flocculant becomes more and more popular for its selective, abundance in raw materials, low prices and non-toxic.
