摘要
分别以引入硫酸铁和聚合硫酸铁的方式合成聚合硫酸硅铁(PFSS和PFS-PS),采用Fe-Ferron和β-Sicilocomobdate 相结合的方法分析两种絮凝剂中硅铁的形态分布,考察Fe/Si摩尔比、碱化度及熟化时间对硅铁形态分布的影响,为聚硅铁絮凝剂研制提供理论基础。
This paper discusses the polymeric ferric silicate flocculants including synthesizing polymeric ferric silicate sulfate floc-culant with ferric sulfate and poly-ferric sulfate respectively, analyzing the species distribution of iron and silicon in the PFSS with Fe-Fer-ron and β-silicomolybdate methods, studying the influence of the ratio of Sihcon/Fe、basicity、aging time on species distribution of silicon and iron. It puts forward the theory foundation of research on polymeric ferric silicate flocculants.
