【摘要】 采取共聚与复合两种制备工艺 ,加入稳定剂 (S) ,合成了具有不同碱化度 (B)的稳定的高浓度聚合氯化铁混凝剂 (PFC)。通过测定zeta电位对其水解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 ,对其除浊性能进行了考察。结果表明 ,在pH >5的范围内 ,PFC比聚合氯化铝 (PAC)的zeta电位有所降低 ,PFC的zeta电位随pH的变化趋势与PAC也有所不同 ;PFC对模拟悬浊水样具有很好的除浊效果更多还原

【Abstract】 A series of polyferric chloride(PFC) which have different basicity( B ) and stabilizing agent(S)/Fe molar ratio have been prepared by means of two kinds of preparation methods. The electrokinetic properties of PFC are tested by zeta potential measurement. The turbidity removing efficiency of PFC is investigated by jar test in the simulated water compared with industrial polyaluminium chloride(PAC). The study results show that the coagulating effectiveness of PFC is better than PAC in removing the turbidity of the simulated water.更多还原
