Study on the synthesis and properties of the polysilicon ferric sulfate

The composite flocculent polymeric silicate sulfate(PFSiS) was prepared and the influencing factors of its flocculation properties were investigated.This article talked about how to make polymer iron sulfate as raw material through hydrogen peroxide one-shot oxidization and then being added with polymerized silicic acid can be prepared by polymerizing water glass in the acid.The primary influence factor flocculation behaviour were optimised.The optimum conditions were as follows: Psi activate reation 3h,SiO2%=2%,Fe∶SiO2=1.0(mole ratio),polymerization in 60℃,ageing time is 4h,product pH value is 1.0.
