摘要
由水玻璃、硫酸和硫酸铁制备聚硅酸硫酸铁（PFSS）混凝剂,用透射电镜观察PFSS的形态,研究了PFSS的形态随硅酸聚合时间、SiO_2/Fe摩尔比和熟化时间的变化。结果表明,硅酸聚合时间、SiO_2/Fe摩尔比及熟化时间对PFSS的形态有较大的影响。
Polymeric ferric silicate-sulfate (PFSS) was prepared by using water glass, sulfuric acid and ferric sulfatc as raw materials. The morphology of PFSS was observed by trans-misson electron microscope (TEM). The variation of morphology of PFSS with the polymerization time, SiO2/Fe molar ratio and aging time was studied. The experimental results show that polymerization time of silicic acid, SiO2/Fe molar ratio and aging time of PFSS have great effect on the morphology of PFSS.
