摘要
研究了在高锰酸钾 /草酸引发体系下 ,淀粉与丙烯酰胺的接枝共聚合反应 ,并将该接枝共聚物作为絮凝剂用于城市污水、造纸污水等的絮凝实验中 ,实验结果表明 ,其 CODCr去除率均略高于聚丙烯酰胺 (3 0 0万 )
Graft copolymerization of starch and acrylamide by potassium permanganate/oxalic acid initiator system is investigated,and this graft copolymer is used in flocculation experiment on the treatment of municipal sewage and paper industry sewage etc.The results show that starch-acrylaimide copolymer performs slightly higher removal efficiency of COD Cr more than PAM product.
