Ferrous sulphate monohydrate (FeSO4.H2O):

Ferrous sulphate monohydrate-manufactured by dry method technical process with perfect mobility of powder and granularapplicable to premixed feed, flocculant for water treatment and removing phosphates from civic and industrial wastewater to avoid eutrophication. Lots of ferrous sulphate are also used to reduce chromates (Cr^{3 +}/Cr^{6 +}) from cement. And kill mosses in garden industries.

CNAME:Ferric sulphate (II) Ferrofallidite

Formula structure:FeSO₄·H₂O

CAS code: 7720-78-7 (anhydrous) | 17375-41-6 (monohydrate)

Physico-chemical specification:

Packing:

- 25kg P.P. bags with inner film or kraft paper bags;1000kg,1250kg or 1350kg flexibags

-Hydration:

It has many kinds of hydrate, some reserve in nature.

·FeSO₄·H₂O (Ferrofallidite)

·FeSO₄· 4H₂O

·FeSO₄· 5H₂O(Fibroferrite)

·FeSO₄· 7H₂O(Green vitriol)

When 90°C, FeSO₄· 7H₂O become FeSO₄·H₂O be dehydration.

Production:

It is the byproducts of iron and steel are wash in sulphuric acid before electroplating or painting.Fe+H₂SO₄=FeSO₄+H₂↑

Alternative ferrous sulphate can also be get from oxidation of pyrite or from reaction of iron and sulphuric acid.

Application:

It is applicable to premixed feed, flocculant for water treatment and removing phosphates from civic and industrial wastewater to avoid eutrophication. Lots of ferrous sulphate are also used to reduce chromates (Cr^{3 +}/Cr^{6 +}) from cement. And kill mosses in garden industries.

Nutrition:

It can be used in treatment of anemia due to lacking iron and can be added in food.

Coloring:

·It is necessary in production of iron gall inks and wood mordant dyeing.

·In the production of Chinese blue, leucoindigo is gotten from insoluble indo-blue dyeing printed on clothes further reduced by ferrous sulphate.

·It can also make the color of concrete to yellow rust-colored.

·Carpenters usually get the silver color of maple painting by ferrous sulphate.
