Ferrous Sulphate Heptahydrate
The ferrous sulphate heptahydrate molecular formula is FeSO4·7H2O, and ferrous sulphate heptahydrate is formed by copolymerization of iron filings, and the appearance of the product is pale green or light yellow crystal. Adding a certain amount can adjust the ph value of the alkaline water, organically combine with the suspended solids in the water, and accelerate the precipitation, mainly used for water purification and industrial wastewater treatment, and has a bactericidal effect.
Ferrous sulfate heptahydrate is prepared by the reaction of dilute sulfuric acid and iron pin. It is a light green or green granular solid. Compared with ferrous sulfate monohydrate, the crystal particles of ferrous sulfate heptahydrate are larger. Ferrous sulfate heptahydrate contains seven crystal water, with a molecular weight of 278.05, the melting point of 69 ℃, and the content of 80-92%. Compared with ferrous monohydrate, ferrous sulfate heptahydrate is easy to oxidize with air.

Application and After-Sales Service:
1.Ferrous sulfate heptahydrate can be used in industrial wastewater treatment, with good decolorization ability and flocculation effect. It also has the functions of removing heavy metal ions, oil, phosphorus, and sterilization; Ferrous sulfate heptahydrate can be used as a reducing agent in electroplating plant, and it has an obvious effect on ferrite coprecipitation of electroplating wastewater; When ferrous sulfate heptahydrate is used in the iron red plant, it can produce magnetic iron oxide, iron oxide red, and iron blue pigment.
2.In agriculture, ferrous sulfate heptahydrate can be used as a pesticide and chemical fertilizer to control wheat smut, apple, and pear scab, fruit tree rot, and remove the moss and lichen from the trunk.
3.In medical food, ferrous sulfate heptahydrate can be used as a local astringent and blood tonic, food iron fortifier, iron nutritional supplement, and fruit and vegetable colorant to keep the fresh color of pickled products.
