Ferrous Sulfate Heptahydrate is one of the most widely used inorganic compounds in both industrial and laboratory settings. Known chemically as FeSO₄·7H₂O, this crystalline substance appears in light green or bluish-green granules. It plays a critical role in sectors ranging from water treatment and fertilizers to mining, construction, and chemical manufacturing.
At City Chemicals Europe (citychemicalseu.com), we pride ourselves on supplying high-purity Ferrous Sulfate Heptahydrate for global industries. Our customers trust us for reliable sourcing, excellent product consistency, and compliance with international quality standards.
What is Ferrous Sulfate Heptahydrate?
Ferrous Sulfate Heptahydrate is a hydrated iron (II) salt containing seven molecules of water. In appearance, it forms pale green crystals that are soluble in water. This compound provides a bioavailable form of iron, making it suitable for both industrial and agricultural applications.
How It Works
-
In Water Treatment – Ferrous Sulfate Heptahydrate acts as a coagulant, helping to remove impurities and phosphorus from wastewater.
-
In Fertilizers – Supplies plants with essential iron, correcting chlorosis and promoting healthy leaf growth.
-
In Mining & Construction – Used in cement colorants, ore flotation, and as a reducing agent in various chemical processes.
-
In Laboratories – Serves as a precursor for the preparation of other iron compounds and analytical testing.
