| 摘 要： | 以壳聚糖为原料，选用Ce^4＋-S2O8^2-复合引发体系作为接枝共聚反应的引发剂，采用水溶液聚合法接枝丙烯酰胺制备环保型高分子絮凝剂。研究引发剂配比对接枝共聚反应的影响。研究结果表明Ce^4＋：S2O8^2-=5：75时所制备接枝物的接枝率和单体转化率最好，并且通过絮凝实验，发现不同投加量的壳聚糖二-丙烯酰胺接枝共聚物对废水试样的絮凝效果不同。

| Abstract: | Chitosan was studied as base material grafting acryl-amide. Ce4+-S2O82-compound initiation system was selected to prepare with friend-environmently polymeric flocculant by solution polymerization. This experiment studied mainly the influence to the reaction about the different compounding proportion of initiation. It was showed that the highest graft rate and monomer percent conversion were achieved with allocated proportion initiator of 5:75. By flocculation experiment,it was found that the flocculanting p... |
