Ferrous sulfate can be used to make iron salts, iron oxide pigments, mordants, water purifiers, preservatives, disinfectants, etc.;

1. Water treatment

Ferrous sulfate is used for flocculation purification of water and removal of phosphate from urban and industrial sewage to prevent eutrophication of water bodies.

2. Reducing agent

A large amount of ferrous sulfate is used as a reducing agent, mainly to reduce chromate in cement.

3. Medicinal use

Ferrous sulfate is used to treat iron deficiency anemia; it is also used to add iron to food. Long-term excessive use may cause side effects such as abdominal pain and nausea.

Medically, it can also be used as a local astringent and blood tonic, and can be used for chronic blood loss caused by uterine fibroids.

4. Colorant

a. The production of iron tannate ink and other inks requires the use of ferrous sulfate. Ferrous sulfate is also contained in mordants for wood dyeing.

b. Ferrous sulfate can be used to dye concrete into a yellow rust color.

c. Carpenters use ferrous sulfate to dye maple wood with a silver color.

5. Agriculture

Adjust soil pH and promote the formation of chlorophyll (also known as iron fertilizer), which can prevent and treat yellowing of flowers and trees caused by iron deficiency. It is an indispensable element for acid-loving flowers and trees, especially iron trees. In agriculture, it can also be used as a pesticide to prevent and treat wheat smut, scab of apples and pears, and fruit tree rot; it can also be used as a fertilizer to remove moss and lichen from tree trunks.

6. Analytical Chemistry

Ferrous sulfate can be used as a chromatographic analysis reagent.
