摘要

基于磷酸根对聚合硫酸铁（PFS）的强增聚作用，以聚合硫酸铁、Na 2HPO 4为原料，研制出一种新型复合絮凝剂聚磷硫酸铁（PPFS）。通过红外图谱（IR）和电镜扫描（SEM）分析，对PPFS的结构进行了表征，对其絮凝机理进行了探讨，并考察了PPFS的投加量、nPO 43-/nFe3+和碱化度对邻苯二甲酸酯类去除效果的影响。结果表明：PPFS对邻苯二甲酸酯类具有良好去除效果，当投加量为70 mg·L-1、nPO 43-/nFe3+为0.3、碱化度为30%时，邻苯二甲酸二甲酯、邻苯二甲酸二乙酯、邻苯二甲酸二丁酯和邻苯二甲酸二（2-乙基己基）酯的去除率分别为67.93%、84.55%、90.88%和88.69%。

Abstract

Based on the strong poly role of phosphate on polymeric ferric sulfate (PFS)

with PFS and Na 2HPO 4 as raw materials

a new type of composite flocculant polymeric phosphate ferric sulfate (PPFS) was developed. The structure of PPFS was characterized by IR and SEM

and the mechanism of flocculation was analyzed. The factors affecting phthalic acid esters (PAEs) removal were discussed

including dosage

nPO 43-/nFe3+and alkalization degree. The results indicate that PPFS has good removal effect to PAEs. When the dosage is 70 mg·L-1

nPO 43-/nFe3+ is 0.3 and alkalization degree is 30%

the removal rate of dimethyl phthalate

diethyl phthalate

dibutyl phthalate and bis (2 ethylhexyl) phthalate are 67.93%

84.55%

90.88%

88.69%

respectively.
