Ferrous sulfate (alum) molecular formula FeSO4•7H2O An inorganic compound, anhydrous ferrous sulfate is a white powder, soluble in water, the aqueous solution is light green, commonly found in its heptahydrate (green alum). It is mainly used for water purification, photo plate making and treatment of iron deficiency anemia. Ferrous sulfate can cause pollution to water bodies, irritate the human respiratory system and digestive system, and excessive consumption can lead to life-threatening.

Restorative. Toxic gases are liberated by high heat content. In the laboratory, it can be obtained by reacting a solution of copper sulfate with iron. Weathering occurs in dry air. In humid air, it is easily oxidized into brownish yellow alkaline iron sulfate that is difficult to dissolve in water. The 10% aqueous solution is acidic to litmus (ph value of about 3.7). Heating to 70 ~ 73 °C to lose 3 molecular water, to 80 ~ 123 ° C to lose 6 molecular water, to 156 ° C above the transformation into alkaline iron sulfate. [1]

Ferrous sulfate can be used for iron salts, iron oxide pigments, mordants, water purification agents, preservatives, disinfectants, etc.;
ferrous sulphate

1. Water treatment
Ferrous sulfate is used for flocculation purification of water, as well as to remove phosphate from municipal 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 reducing chromate in cement.
3. Medicinal
Ferrous sulfate for the treatment of iron deficiency anemia; It is also used to add iron to food, and long-term overuse may cause side effects such as abdominal pain and nausea.
It can also be used as a local astringent and blood tonic in medicine, and can be used for chronic blood loss caused by uterine fibroids

4. Colorants
a. The production of ferric tannate ink and other inks requires the use of ferrous sulfate. Wood-dyed mordants also contain ferrous sulfate.
b. Ferrous sulfate can be used to dye concrete yellow rust color.
c. Woodworking with ferrous sulfate to dye maple wood silvery color.

5. Agriculture
Adjust the soil pH, promote the formation of chlorophyll (also known as iron fertilizer), can prevent the yellowing disease caused by iron deficiency in flowers and trees. It is an indispensable element of acid-loving flowers and trees, especially iron trees. It can also be used as a pesticide in agriculture to prevent wheat smut disease, apple and pear scar scab disease, and fruit tree rot disease; It can also be used as fertilizer to remove moss and lichen from the trunk.

1.As a reducing agent: ferrous sulfate is a strong reducing agent, can be the water content of the electroplating plant chromium wastewater hexavalent chromium reduction into trivalent chromium.

2.As a flocculant: ferrous sulfate is widely used as a flocculant, it has the following advantages as a flocculant: Sedimentation speed, large granular sludge, the sludge volume small and compact, except for the color effect is good, very suitable for as a textile wastewater, printing and dyeing, washing processing), non-toxic and beneficial organisms (very suitable for use in the subsequent biochemical treatment process of wastewater treatment system), without changing the original technology, and the price is low, as a flocculant, Ferrous sulfate can replace polymeric aluminum, basic aluminum chloride, polymeric iron, aluminum sulfate and so on. Dyeing, electroplating and other wastewater treatment worthy of the product.
3.As a precipitator: ferrous sulfate and sulfide, phosphate and other precipitation, so as to remove sulfide, phosphate, etc., for example, with ferrous sulfate treatment of printing and dyeing plant sulfur wastewater.
