Ferrous Sulfate Heptahydrate

Ferrous sulfate heptahydrate is green in color, monoclinic or granular, and odorless.

Relative density 1.898, melting point 64°C. It is readily soluble in water (48.6 g/100 ml water). It decomposes red-hot at 50°C to form ferric oxide. It is soluble in glycerol, is corrosive, and weathers in dry air. At 56.6°C, the heptahydrate converts to a tetrahydrate, and at 64.6°C, it becomes a monohydrate. At 90°C, six waters of crystallization are lost, and at 300°C, all waters of crystallization are lost, forming an anhydrous substance. Upon red-hot heating, SO₂ and SO₃ decompose and release SO₃. It is corrosive and fluoresces in dry air. The anhydrous substance is a white powder, but turns bluish-green when mixed with water.

Product Applications
1. Water Treatment
2. Reducing Agent
3. Pharmaceutical Use: Ferrous Sulfate is used to treat iron-deficiency anemia
4. Colorant
a. Ferrous sulfate is required for the production of iron tannate ink and other inks.
b. Ferrous sulfate can be used to dye concrete a yellow rust color.
c. Ferrous sulfate is used to create maple-silver wood.
5. Agriculture: Used to adjust soil pH.

Product Features
1. A new, high-quality, and highly efficient iron salt inorganic polymer water purifier, coagulant, and flocculant.
2. Contains 22% active ingredient Fe₃⁺, resulting in excellent coagulation performance, dense alum flocs, and rapid settling. Complete settling takes 5-30 minutes, and the use of auxiliary settling facilities results in even faster settling times.
3. Excellent water solubility, low in insoluble matter and heavy metal content, resulting in excellent water purification and stable effluent quality.
4. Stable performance: Dissolved solution can be stored for extended periods without precipitation, deterioration, or pipe clogging.
5. Excellent decolorization, dehydration, deoiling, and phosphorus removal, as well as heavy metal ion removal, with strong COD and BOD removal capabilities.
6. Effectively prevents the health risks of excessive aluminum ion levels in drinking water caused by aluminum salt water purifiers.
7. Suitable for water with a pH range of 4-11, with a pH of 7-8 being optimal. The pH value after purification exhibits minimal fluctuation, reducing water hardness.
