摘　　要：使用预辐照方法对金属离子附载后的天然高分子进行活化,再引发水溶性单体接枝共聚,制备具有离子附载的高支化聚丙烯酰胺共聚物.使用红外分光计(FTIR)、紫外分光计(UV)和黏度剂表征聚合物结构并评价絮凝性能.研究表明,金属离子是以螯合状态存在于聚合物结构中,并可在水溶液中逐步析出.在预辐射体系中引入多价金属离子并未影响接枝共聚物的水溶性,并且明显提高了絮凝效率.The ion chelated high-branching acrylamide copolymer flocculant is prepared using pre-irradiation activation method of the nature polymer chelated with metal ion and grafted with water soluble monomer. The product is characterized and evaluated with FTIR, UV and rotation viscosity meter. Experiment results show that the ion is chelated on the polymer and could be released gradually. The introduction of muhivalent ion not only did not influence the solubility of the copolymer, but also increase the flocculation efficiency.
