摘要 本文合成了一系列不同阴、阳离子度的强碱弱酸型的两性聚电解质[丙烯酰胺(AM)-二甲基二烯丙基氯化铵(DMDAAC)-丙烯酸(AA)共聚物]。研究了阴、阳离子单体的配比对两性聚电解质分子量的影响;以及两性聚电解质阴、阳离子度对絮凝效果的影响。并将所合成的两性聚电解质作为絮凝剂,首次应用到黄河高浊度水的处理中。填补了国内两性聚电解质高分子絮凝剂应用于上水的空白。研究结果表明:在等电点范围内的两性聚电解质对黄河高浊度水的絮凝效果明显优于传统的非离子型、阳离子型及阴离子型絮凝剂。

Abstract: In this paper,various charge densities acrylamide-based polyampholytes [the copolymer of acrylamide(AM),dimethyldiallylammonium chloride(DMDAAC) and acrylic acid(AA)] were synthesized.The influence of ratio of cationic and anionic monomers on molecular weight of ampholytic polyelectrolytes and influence of cationic and anionic content in ampholytic polyelectrolytes on flocculation effects have been investigated.These polyelectrolytes were applied to treatment of the high turbidity water of the Huanghe River as a flocculant,this practical application is the first test in our country.The results show that inter isoelectric point range of polyampholytes,its function is much better than the convention flocculants,such as non-ionic,cationic or anionic flocculants.
