摘　　要：通过测定Zeta电位对聚合氯化铝铁(PAFC)水解产物的电动特性进行了研究。通过对模拟悬浊水样的絮凝实验对PAFC除浊性能进行了考察。结果表明:PAFC水解产物的电动特性与pH、PAFC投加量和Al/Fe摩尔比的变化密切相关;PAFC是通过电中和、吸附架桥和卷扫作用起混凝作用的,3种作用的综合能力越强,其混凝效果就越好。The electrokinetic properties of polyaluminium ferric chloride （PAFC） were tested by zeta potential measurement under different pH condition, various dosages and different Al/Fe molar ratio. The turbidity removal efficiency of PAFC was investigated by jar test with a synthetic water sample. The experiment results showed that the coagulation of particles by PAFC polymers in this water was through the following mechanisms： charge neutraliza- tion,adsorption bridging and precipitation sweeping, with the first two dominating. The better the synthesis of the three mechanisms, the better the coagulation effect.
