摘　　要：以二甲胺与环氧氯丙烷制得的氯化聚2-羟基-1-N-甲基铵和丙烯酰胺为单体,采用过硫酸铵和亚硫酸氢钠复合引发剂聚合得到了高电荷密度的新型阳离子型聚丙烯酰胺絮凝剂.优化了絮凝剂的合成条件,利用红外光谱分析对最终产物的结构进行了表征.以造纸废水和模拟的印染废水对絮凝剂性能进行了测定,结果表明该有机絮凝剂和无机絮凝剂混合使用有很好的协调能力,能有效减少无机絮凝剂的使用量,降低水处理成本、提高净水效果.A new kind of pulyacrylamide cation flocculating agent with high charge density was prepared with the chlorination polymer 2- hydroxyl-1- N- methylhistamine and acrylamide as the raw materials, K2S2O8 and NaHSO3 as compound initiator. The influences of the reaction condition were investigated. The structure of flocculating agent was characterized by infra-red spectrum. The floccuiation ability of this flocculating agent was determined by dye waste water and papermaking waste water. The resuits show that the organic flocculating agent and inorganic flocculating agent have good coordination abilities, which can reduce the using amount of inorganic flocculating agent, lower the water processing cost and raise the water-cleanning effects.
