| Abstract: | Poly-ferric sulfate（PFS） is a kind of efficient inorganic polymer flocculants,it is widely used in waste water treatment.In this paper,effects of oxidizer dosage,reaction temperature,sulfuric acid dosage,reaction time and product stability on preparation of poly-ferric sulfate were investigated.The results show that the appropriate conditions are as follows： temperature is 25 ℃,molar ratio of FeSO4,H2SO4 and H2O2 is 1：0.26：0.6,polymerization time is 2.5 h,product is stability in 144 h,the total icon and basicity of PFS prepared under above conditions accord with the industrial standard and national standard. |
