【摘要】 合成了一系列带不同阴、阳离子基团含量的两性高分子絮凝剂 ,详细讨论了阴、阳离子基团含量对硅藻土悬浮体系絮凝性能 (透光率、沉降速度、沉降体积 )的影响。结果表明 :阴、阳离子基团含量并不是越大越好 ,它们之间有个协同效应 ,基团含量太大或太小对絮凝作用都不利更多还原

【Abstract】 In this paper,a series of amphoteric polymeric flocculant containing different anionic and cationic group content were synthesized by radical copolymerization.The influene of anionic and cationnic group content of flocculant on flocculation perfomance were investigated in detail,the experimental results showed that:when containing 10 mol% cationnic group and 2～4 mol% anionic group,the flocculant exhibited optimum flocculation behavior.更多还原
