摘要
以硫酸铁、磷酸三钠为原料 ,合成出 Fe3+/PO3-4不同摩尔配比的聚合磷硫酸铁 (PFPS)。结果表明 :PFPS的性能优于 PFS,表明了 PO3-4对 PFS有显著的增聚作用。
Polyferric phosphate sulfate(PFPS), a new coagulant, was synthesized by adding PO 3- 4 to polyferric sulfate. The optimum condition of synthetic PFPS was selected by orthogonal design test. The effects of Fe 3+ /PO 3- 4 molar ratio, pH and PFPS adding amount on coagulation effects were examined. Compared with PFS, PFPS, it showed better performance in removal of turbidity and decoloring. The addition of PO 3- 4 improved PFS polymerization and coagulation and coagulation properties.
