Iron (II) Sulphate Heptahydrate (Ferrous Sulphate)

What is Iron (II) Sulphate Heptahydrate (Ferrous Sulphate)? Iron (II) Sulphate Heptahydrate, also known as Ferrous Sulphate, is a high-purity crystalline compound that consists of iron, sulphur, and water molecules. It is typically found in its heptahydrate form, meaning it contains seven water molecules per formula unit. This compound is widely used in various industrial, agricultural, and pharmaceutical applications, particularly for its iron content, which makes it useful for plant nutrition.

Frequent Uses

Agricultural Applications
Commonly used in agriculture as a fertiliser to correct iron deficiencies in plants. It is an effective source of iron for crops, preventing chlorosis (yellowing of leaves) caused by insufficient iron. It is used in soil treatment to promote healthy plant growth, especially in plants such as lawns, shrubs, and fruit trees that require optimal iron levels.

Water Treatment
Widely used in water treatment to remove impurities. It is particularly effective in treating wastewater, where it is used as a flocculant to help remove suspended solids. Iron (II) Sulphate helps to precipitate unwanted particles, making it easier to purify water and improve its quality for both industrial and municipal uses.

Pharmaceutical and Nutritional Applications
In the pharmaceutical industry, it is commonly used as an iron supplement to treat iron deficiency anaemia in humans. It is formulated into tablets, capsules, and liquid preparations to help replenish iron levels in individuals who are deficient. This compound is an important source of bioavailable iron, aiding in the formation of red blood cells and preventing fatigue and weakness.

Cosmetic and Personal Care
Iron (II) Sulphate is used in the cosmetics industry as a colourant and pigment in various products, including make-up, hair dyes, and other personal care products. Its distinct greenish colour is often employed in products where a subtle, natural tint is desired.

Leather Tanning
Plays a role in the leather tanning process, where it is used to create certain types of leather, particularly in the production of light-coloured or pale leather. It acts as a mordant, helping to fix the dye to the leather and enhancing the tanning process.

Industrial and Manufacturing Uses
In various industrial applications, it is used as a reducing agent in chemical processes and in the production of other iron compounds. It is also used in the preparation of pigments, inks, and in the manufacture of certain dyes. Additionally, it is employed in the production of ferrous-based materials and as a catalyst in certain industrial reactions.

Environmental and Soil Remediation
Used in environmental applications, such as in the treatment of contaminated soil or as a chemical agent for reducing the bioavailability of heavy metals. It helps to immobilise harmful substances, such as arsenic or lead, preventing them from leaching into water systems and reducing environmental pollution
