| 摘 要： | 利用过硫酸钾、亚硫酸氢钠、偶氮二异丁腈及其它助剂组成的复合引发体系,研究了在30℃下,丙烯酰胺(AM)与N,N-二甲基二烯丙基氯化胺(DMDAAC)在水溶液中的共聚合,得到了溶解性能好的阳离子共聚物(PDA).考察了pH值、引发剂用量和单体加料方式对阳离子共聚物粘度和阳离子度的影响.继而进一步研究了PDA作为絮凝剂在污泥脱水中的应用,其污泥脱水效果比目前市售的阳离子絮凝剂要好.

| Abstract: | Polyacrylamide-dimethyldiallylammonium chloride Copolymer(PDA) was synthesized by multi-initiating system,which includes potassium peroxydissulfate,sodium hydrogen sulphite,2,2'-azobis(isobutyronitrile) and other additives.The effects of pH,amount of initiator and adding way of monomer on viscosity and cationic degree were studied.The PDA takes on good solubility and flocculability. |
