近年来，无机/有机复合絮凝剂作为污水处理中的较新手段，日益受到重视[3]。其中聚丙烯酰胺是目前世界上应用最广、效能较高的高分子有机合成絮凝剂。这主要是由于聚丙烯酰胺的酰胺基可与许多物质亲和、吸附形成氢键。高相对分子质量的聚丙烯酰胺在被吸附的粒子间形成“桥联”，使数个甚至数十个粒子连接在一起，生成絮团，加速粒子下沉，这使它成为理想的絮凝剂[4]。高分子絮凝剂的絮凝机理与其结构密切相关，多支型结构的絮凝剂由于采取更为伸展的构象，因而可能获得普通线形高分子絮凝剂所不具有的絮凝效果。本实验采用高价铈盐和多官能度的小分子有机物季戊四醇作为氧化还原体系引发丙烯酰胺自由基聚合合成得到了一种多支状阴离子型聚丙烯酰胺，对其性能进行了较系统探索，为这种多支状聚丙烯酰胺的应用奠定一定理论基础 求高手帮忙啊 十万火急！！！ |

In recent years, inorganic / organic composite flocculant for wastewater treatment in a relatively new means of increasing attention [3]. Polyacrylamide which is the world's most widely used, high performance polymer flocculant organic synthesis. This was mainly due to amide polyacrylamide affinity with many substances, adsorption to form hydrogen bonds. High molecular weight polyacrylamide was adsorbed particles in the formation of "bridging" so that even several dozens of particles connected together to produce floc, accelerated particles sink, making it ideal flocculant [ 4]. Mechanism of polymer flocculant is closely related to its structure, multi-branch structure of the flocculant As a result of a more extended conformation, which may be general do not have a linear polymer flocculant flocculation. In this study the high degree of cerium salt and multi-functional small molecule organic compounds of pentaerythritol as a redox free radical polymerization of acrylamide has been a multi-branch-like anionic polyacrylamide, its performance was systematically explored for this kind of multi-branch-like application of polyacrylamide to lay a certain theoretical basis. 翻译的不是不好 ！！呵呵 |
