摘要 以具有不同碱化度 (B)的聚合氯化铝 (PAC)和二甲基二烯丙基氯化铵均聚物 (PDMDAAC)为原料 ,制备出了系列PAC PDMDAAC ,采用微电泳技术研究了其电动特性 ,初步试验了处理黄河水的絮凝效果 .研究结果表明 ,PAC PDMDAAC较PAC具有更高的正Zeta电位值与更好的除浊效果 .PAC的B值和PDMDAAC质量分数(P)对PAC A series of composite flocculants polyaluminium chloride (PAC)-polydimethydiallyammonium chloride (PDMDAAC) was prepared by using PAC with different basicity ( B ) and PDMDAAC was raw materials. The electrical charge of PAC-PDMDAAC was studied by electrophoretic mobility method. And the flocculating efficiency of PAC-PDMDAAC on treating water from Yellow River was also preliminarily examined by Jar-test. The experimental results show that the PAC-PDMDAAC is characterized by giving higher positive Zeta potential value and better flocculating effect than PAC. The B value of PAC and the content ( P ) of PDMDAAC in PAC-PDMDAAC had some effect on the Zeta potential and the turbidity-removal efficiency.
