【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.更多还原

【Abstract】 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.更多还原
