摘要

Abstract

A new type of inorganic polymer coagulant

poly-aluminum ferric silicate sulfate(PAFSS)

was prepared by alkali leaching

acidic leaching

oxidation

and polymerization.Fly ash

crap iron and waste sulfuric acid were utilized as raw materials.The structure

morphology and coagulation property of the sample were characterized by XRD

TEM

microelectrophoresis

ultrafiltration and coagulation experiments.The results showed that the multi-core PAFSS sample

which possessed larger amounts of Al-O-Si and Fe-O-Si

was synthesized from the interaction between Fe3+

Al3+

their hydrating polymers

SO42- and poly-silicic acid.The polymer displayed branch-like structure with higher polymerization degree

and larger molecular weight.The coagulation property of samples was excellent when the Si/(Fe+Al)ratio was equal to 0.06-0.10.pH adaptability was much better than that of commercial polymerized ferric sulfate(PFS)

polymerized aluminum chloride(PAC)and poly-aluminum ferric sulfate(PAFS).
