PAFC对水体中持久性有机污染物PFOA的混凝效果
Coagulation effects of persistent organic pollutant PFOA in water by PAFC
摘要
Abstract
Perfluorooctanoate (PFOA) as one of emerging contaminants,has been attracting increasing concerns in recent years.Model solution was treated using primary flocculant polyaluminum ferric chloride (PAFC) and coagulant aid attapulgite or zeolite were conducted in this work.The experimental results showed that the removal rate of PFOA and turbidity reached 70.25％ and 99.42％,respectively at the optimal PAFC dosage of 10 mg/L,and the removal effect of PFOA by PAFC was better than PAC.The removal rate of PFOA is significantly affected by the pH value of solution,and the maximum removal of PFOA is obtained at the near neutral solution pH value.The removal rate of PFOA and turbidity increases with the increasing in initial turbidity.The removal rate of PFOA is enhanced by PAFC combined with some coagulant aid,such as activited carbon,hydrochloric acid modified attapulgite and zeolite,CTMAB modified zeolite.Using PAFC and the modified zeolite maybe is an efficient and feasible method to remove PFOA from water.关键词
