Ferrous Sulphate/Ferrous Sulfate/ FeSO4.7H2O

Name: Ferrous Sulfate

Molecular Formula: FeSO4.H2O/FeSO4.7H2O

Molecular Weight: 278.05

CAS Code: 7782-63-0



The appearance of the product is light green or yellowish green, crystalline solid, tasteless, the relative density is 1.898, and the melting point is 64 degrees. Dissolved in water (50 48.6g/100ml), red hot decomposes to form Fe2O3. It is corrosive and weathered in dry air, which is easy to be oxidized by wet air. Adding the agreed dosage can regulate the pH of alkaline water, combine with the suspended matter in water, and accelerate the precipitation, which is mainly used in water purification and industrial waste-water treatment, and has bactericidal effect at the same time. 


Ferrous sulfate is mainly used as a precursor to other iron compounds. It is a reducing agent, for the reduction of chromate in cement. 

1.Ferrous sulfate is used in Nutritional Supplement. Together with other iron compounds, ferrous sulfate is used to fortify foods and treat iron-deficiency anemia. Constipation is a frequent and uncomfortable side effect associated with the administration of oral supplements. Stool softeners often are prescribed to prevent constipation. 

2.Ferrous sulfate is used in Colorant Ferrous. sulfate can also be used to stain concete and some limetones and sandstones a yellowish rust color. 

3.Ferrous sulfate is used in Water Treatment. Ferrous sulfate has been applied for the purification of water by flocculation and for phosphate removal in municipal and industrial sewage treatment plants to prevent eutrophication of surface water bodies.
