摘要

应用Si-Mo逐时络合比色形态表征法

对无机高分子复合絮凝剂聚硅硫酸铁（PFSS）中硅的形态进行了研究，包括SiO2反应速率特征及其标准工作曲线，不同pH值条件下聚硅酸（PSi）的形态分布特征，不同pH值时PFSS与PSi中硅的形态特征比较。结果表明：不同pH值的PFSS中，硅的聚合形态熟化一定时间后，分布规律有所不同。pH值为1.46和1.70时，PFSS中硅酸的中聚体含量比pH值为0.64时的高，而pH值为0.64时，PFSS中硅酸的高聚态、凝胶态含量明显高于pH值为1.46和1.70的相应含量。同时，pH值为1.46和1.70的PFSS比pH值为0.64的PFSS有更好的絮凝性能和稳定性。由此可知，PFSS中聚硅酸的优势形态是其中聚体。

Abstract

The Si species distribution of inorganic polymer flocculant polyferric silicate sulfate (PFSS) was studied by chemical Si-Mo assay.The study included reaction rate characteristics and standard work curve of SiO2

polysilicic acid (PSi) species distribution characteristics at different pH values

and comparison of Si species distribution characteristics of PFSS and PSi at different pH values .The experimental results showed that Si species distribution characteristics in PFSS were variable at different pH values.The content of Sib of silicic acid in PFSS at pH values 1.46 and 1.70 was higher than that of silicic acid in PFSS at pH value 0.64

while the contents of high polymer state and gelatinous state in PFSS at pH value 0.64 were obviously higher than those in PFSS at pH values 1.46 and 1.70.Simultaneously

the study results also showed that PFSS at pH values 1.46 and 1.70 had better flocculability and stability than PFSS at pH value 0.64

therefore the superior state of silicic acid in PFSS was Sib.
