| 摘 要： | 通过实验制备了一种新型无机高分子絮凝剂聚硅硫酸铁（PFSS），用Ferron逐时络合比色法测定了PFSS中铁的形态，考察了熟化时间、Fe3+／SiO2摩尔比对铁的形态分布及转化规律的影响。不同Fe3+／SiO2摩尔比的PFSS中Fe（a）的量最多、占50％以上，Fe（c）在35％～50％之间，Fe（b）在0～5％之间。研究表明：铁的形态分布及其转化规律与溶液的高酸度及聚硅酸的存在有关。

| Abstract: | By means of experiment,authors made a new type of inorganic polymer flocculant, i. e. poly-ferric sil-sulfate (PFSS), determined the iron form by Ferron time by time complexation colorimetry,observed aging time and the effect of Fe3+/SiO2mole ratio upon iron form distribution and conversion patterns. The amounts of Fe(a) inPFSS of different Fe3+ /SiO2 mole ratios might up to over 50%,while the Fe (c) rangedfrom 35% to 50%,Fe(b) 0～5%. The study showed that the iron form distribution andits conversion patterns were relevant to existing high acidity and polysilicate in solution. |
