摘　　要：以硅酸钠、硫酸和聚合硫酸铁 (简称 PFS)为原料制备活笥硅酸聚合硫酸铁 (简称 ASPFS)。测定了 ASPFS红外光谱 ,研究了 Fe/Si摩尔比和水样 p H值等因素对产品性能和除浊效果的影响 ,当 Fe/Si摩尔比为 1 .5时产品稳定性和除浊效果均较好。In this paper, the method that activated silicon acid polyferric sulfate(ASPFS)was prepared with Na 2SiO 3,H 2SO 4 and polyferric sulfate(PFS). The IR spectroscopy of ASPFS was identified. The product quality and the effect of remove turbidity was determined by the pH and Fe/Si (mol/mol)ratio of the product. Fe/Si(mol/mol)=1.5,the product was satisfactory.
