摘　　要：聚硅酸铝铁是一类性能优良的新型无机高分子絮凝剂,近来引起国内外研究者的普遍关注。笔者用铝和铁的硫酸盐及盐酸盐与聚硅酸通过共聚法获得了几种不同的聚硅酸铝铁。通过实验得到了各自的最佳絮凝性能的水解度值。然后对最佳产品进行不同浊度和水体酸度的絮凝性能比较,并且分析了对它们性能上的差异。最后讨论了4种絮凝剂在除磷方面的应用。Polysilicate metal salt exhibits excellent flocculation ability. Polysilicate aluminum ferric（PSAF） was prepared through copolymerization by sulphates and chlorides of aluminum or iron with polysilicate acid. The optimal hydrolysis parameter of different PSAFs was determined. Differences in turbidity and flocculation function of four types of PSAFs were evaluated. Furthermore, differences in coagulation and phosphorus removal were analyzed and discussed.
