What is Ferrous Sulphate Monohydrate?

Feb. 14, 2023

Ferrous sulfate monohydrate, also known as iron(II) sulfate monohydrate, is a chemical compound with the formula FeSO4.H2O. It is a hydrated form of ferrous sulfate, which means that it contains one molecule of water for every molecule of ferrous sulfate. This compound is a pale blue-green crystalline powder that is soluble in water.


Ferrous Sulphate Monohydrate


Ferrous sulfate monohydrate is commonly used as a feed additive for animals to prevent or treat iron deficiency anemia. It is a source of bioavailable iron, which is necessary for the production of hemoglobin in red blood cells. Ferrous sulfate monohydrate can also have other benefits, such as improving growth and feed efficiency in some species. However, it should be used carefully as excessive amounts can be toxic to animals.

Ferrous sulfate monohydrate is also an important industrial chemical with a wide range of applications. One of the most common uses of ferrous sulfate monohydrate is as a source of iron in various industrial processes. It is also used in the production of pigments, dyes, and other chemicals. In addition, ferrous sulfate monohydrate is used in the treatment of iron-deficiency anemia and other medical conditions.

The primary source of ferrous sulfate monohydrate is from the treatment of waste solutions produced by the steel industry. During the production of steel, various waste streams are generated that contain iron(II) sulfate. This waste is typically treated with an oxidizing agent, such as air or hydrogen peroxide, to convert the ferrous sulfate to ferric sulfate. The ferric sulfate is then used in the production of other chemicals, while the remaining ferrous sulfate is crystallized to produce ferrous sulfate monohydrate.

Ferrous sulfate monohydrate is also produced by the reaction of iron with sulfuric acid. In this process, iron filings are added to a solution of sulfuric acid, and the resulting mixture is heated. The reaction produces hydrogen gas and ferrous sulfate monohydrate, which can then be recovered by filtration and crystallization.

In the production of pigments, ferrous sulfate monohydrate is used as a precursor to iron oxide pigments. Iron oxide pigments are widely used in the production of paints, coatings, and other products. The pigment is produced by the controlled oxidation of ferrous sulfate monohydrate to produce ferric oxide. The resulting pigment can vary in color depending on the specific conditions of the oxidation process.

Ferrous sulfate monohydrate is also used as a mordant in the dyeing of textiles. A mordant is a substance that is used to fix dyes to fabrics. Ferrous sulfate monohydrate acts as a mordant by binding to the fabric and the dye molecule, which helps to create a permanent bond between the two. This process is commonly used in the production of natural dyes, which can be difficult to fix to fabrics without a mordant.

In addition to its industrial uses, ferrous sulfate monohydrate is also used in the treatment of medical conditions. Iron-deficiency anemia is a common condition in which the body does not have enough iron to produce hemoglobin, the protein in red blood cells that carries oxygen throughout the body. Ferrous sulfate monohydrate is often prescribed to treat this condition because it is a source of easily absorbed iron.

Ferrous sulfate monohydrate is also used in the treatment of other medical conditions, such as restless leg syndrome and attention deficit hyperactivity disorder (ADHD). In these conditions, iron supplementation may help to improve symptoms by increasing the levels of iron in the body.


However, like any chemical compound, ferrous sulfate monohydrate can be dangerous if not handled properly. It is important to follow appropriate safety precautions when working with this compound, including wearing protective equipment such as gloves and eye protection. For more information, please contact us.
