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。
Sodium silicate, sulfuric acid and polyferric sulfate (PFS) were used as raw materials to prepare living silicate polyferric sulfate (ASPFS). The effects of Fe / Si molar ratio and water sample p H value on the performance and turbidity removal were investigated. The stability and turbidity removal efficiency of the product at 1.5% Fe / Si molar ratio better.
