摘　　要：研究氯化铁(FeC l3)-二甲基二烯丙基氯化铵均聚物(PDMDAAC)和聚合氯化铁(PFC二)-甲基二烯丙基氯化铵均聚物(PDMDAAC)复合絮凝剂的水解历程、水解产物的特性和电荷特性,考察絮凝剂的水解对脱色效果的影响.结果表明,复合絮凝剂与FeC l3和PFC相比,具有水解速度快,水解稳定期长,表面电荷高,pH适用范围广的特点.The composite flocculant ferric-trichloride （ FeCl3） -polydimethydiallyammonium chloride （ PDMDAAC ）, and composite flocculant polyferric（ PFC ）-polydimethydiallyammonium chloride（ PDMDAAC ） were studied by particle characterization systems and electrophoretic mobility method, respectively. And the effect of coagulate hydrolyze on color removal was also preliminarily examined by Jar-test. The results show that the composite flocculants hydrolyzed in higher velocity and the hydrolysate of them were more stable and had higher Zeta potential than FeCl3 and PFC, so composite flocculant can be used in wider pH range than FeCl3 and PFC.
