What is Iron Sulfate Monohydrate?
Iron sulfate monohydrate (FeSO₄·H₂O) is the more concentrated and stable hydrated form of iron(II) (ferrous) sulfate.ron sulfate monohydrate (FeSO₄·H₂O) is the more concentrated and stable hydrated form of iron(II) (ferrous) sulfate. It typically contains ~30% elemental iron; its chemical function is the same as heptahydrate (source of Fe2⁺). For this reason, it is evaluated in.
Main Areas of Use
1) Agriculture (Plant Nutrition & Soil Conditioner)
• Chlorosis correction: Used for correcting iron deficiency (chlorosis) in alkaline/lime-rich soils or through foliar application.riculture (Plant Nutrition & Soil Conditioner)

• Chlorosis correction: Used for correcting iron deficiency (chlorosis) in alkaline/lime-rich soils or through foliar application.
• Moss control on lawns: Approved moss killers containing ferrous sulfate are effective in suppressing existing moss on lawns.
2) Feed Additive (Livestock)
• Mineral supplement: Can be safely used as a feed additive in all species at appropriate doses.
3) Water and Wastewater Treatment
• Phosphorus removal/coagulation: Iron salts are common coagulants for P removal and suspended solids removal; ferrous sulfate is used in pilot and full-scale applications.

• Odor and corrosion control (H₂S): Precipitates sulfur in sewage/wastewater systems, reducing H₂S-induced odor and corrosion.
• Chlorite reduction in drinking water: Chlorite (ClO₂⁻) formed during chlor dioxide use can be reduced to chloride by Fe(II).
4) Pigment Production & Coloring
• Raw material for iron oxide pigments: Synthetic iron oxides can be produced by thermal decomposition/precipitation of iron salts such as ferrous sulfate (red, yellow, brown, etc.) • Raw material for iron oxide pigments
5) Cement and Construction • Cr(VI) reduction: Ferrous sulfate (mono/hepta) is the standard additive to reduce the water-soluble hexavalent chromium (Cr(VI)) level in cement to Cr(III) to ≤2 ppm; There are relevant borders in the EU.
6) Chemical Industry • Intermediate: Ferrous sulfate is used as a precursor in the production of other iron salts, especially ferric sulfate. • Fenton oxidation (AOP): FeSO₄, together with H₂O₂, is the typical source of Fe(II) for the Fenton reagent; It is a common method for oxidative degradation of challenging organics.
7) Environment & Soil Reclamation • Chromate (Cr(VI)) reduction and immobilization: Ferrous sulfate has been used in field studies for the purpose of reducing and binding Cr(VI) → Cr(III) in contaminated soil/water environments (case studies and current academic studies are available).
8) Historical Textile & Leather Applications
• Mordant and iron-tannate dyes: Iron(II) ions form iron-tannate complexes with natural tannins; historically used for black/grey tones in textile and some leather dyeings (limited/traditional today).
