| 摘 要： | 以环氧氯丙烷和二甲胺为原料，乙二胺为交联剂，制备有机阳离子聚合物，研究乙二胺加入量、反应温度、环氧氯丙烷和二甲胺的摩尔比、聚合时间等对聚合物粘度和阳离子度的影响，利用电子透射电镜(TEM)和电子扫描电镜(SEM)对聚合物的结构形貌进行了表征，结果表明，环氧氯丙烷和二甲胺的摩尔比为1．5：1，乙二胺加入量为3％时，聚合物的粘度和阳离子度最大，具有较强的吸附架桥和电中和作用，对染料废水有较好的脱色效果。

| Abstract: | Polyamine flocculants were synthesized by polycondensation of dimethylamine and epichlorohydrin with 1 ,2-diaminoethane as modifying agent. The influences of the amount of 1,2-diaminoethane, temperature, molar ratio of epichlorohydrin and dimethylamine, and time on the viscosity and cationic degree of polyamine flocculants were investigated. TEM and SEM were used to test the structure and figure of polyamine flocculants. The results show that when molar ratio of epichlorohydrin and dimethylamine is set as 1. 5: 1 and the amount of 1,2-diaminoethane is 3% , polyamine flocculants get the best viscosity and cationic degree and have excellent decoloration efficiency through the adsorption and subsequent formation of particle-polymer-particle bridges. |
