Detailed
What is Ferrous Sulphate Monohydrate Granular
Ferrous Sulphate Monohydrate Granular is an inorganic compound granule with "ferrous sulphate monohydrate" as its core component, having the chemical formula FeSO₄·H₂O (each ferrous sulphate molecule binds to 1 water molecule). It is one of the common hydrate forms of ferrous sulphate (other common forms include heptahydrate FeSO₄·7H₂O and anhydrous FeSO₄), processed into granular form through specific techniques to balance functionality and practicality.
Core Features
1.Composition & Purity:The main component is FeSO₄·H₂O, with iron (Fe) content ≥30% (dry basis). Impurities (e.g., heavy metals like lead, arsenic, cadmium) strictly comply with industrial/feed-grade standards (e.g., GB/T 10531-2016 "Water Treatment Agent Ferrous Sulphate").
2.Physical Form:It appears as regular granules (common particle sizes: 6-12 mesh, 12-24 mesh, or custom specifications), distinguishing it from powders or blocks. Granules feature smooth surfaces, good flowability, low dust content (<0.5%), and are easy to store, transport, and use.
3.Stability & Functionality:
①.Low Hygroscopicity: With only 1 water molecule, it is less prone to moisture absorption and caking than heptahydrate (7 water molecules) (caking rate <1% under normal temperature/humidity after 3 months);
②.Easy Dissolution: Solubility ≈28g/L in water at 20℃, fully dissolving within 3 minutes to release Fe²⁺ ions;
③.Slow-Release Property: Granular structure enables gradual iron ion release, reducing leaching loss (fertilizer utilization rate increased by >30% compared to powder).

Application
1）Agricultural Applications & Fertilizer Use
Ferrous sulfate monohydrate is widely used in agriculture as a source of iron fertilizer to enrich soil with iron. It helps improve photosynthesis and plant growth, particularly in soils suffering from iron chlorosis.
2）Animal Feed & Healthy Animal Feed Blocks
Ferrous sulfate monohydrate is used as an animal feed additive to provide essential iron, especially for animals with iron deficiency, such as poultry and swine. Iron is a critical component of hemoglobin in animal blood, and its deficiency can lead to anemia.
3）Industrial Applications
In industrial applications, ferrous sulfate monohydrate is widely used in water treatment, wastewater treatment, and soil remediation. It effectively removes heavy metal ions from water, particularly when treating water and soil contaminated with excessive heavy metals, due to its strong precipitation properties.
4）Other Uses
Ferrous sulfate monohydrate is also used as an iron source in food additives, lawn fertilizers, and certain reactions in fertilizer production. It is also employed in the production of certain chemicals, particularly in corrosion protection in the steel industry and in the manufacture of bleaches.

Storage Environment Requirements
✦Temperature & Humidity Control: Optimal storage temperature: -10℃~40℃ (extreme heat may accelerate slow hydrolysis; ≤-10℃ may embrittle packaging). Humidity must be <60% (≥70% humidity causes 15% caking within 3 days).
✦Ventilation & Light Protection: Store in cool, well-ventilated warehouses, away from direct sunlight (UV may slightly accelerate oxidation, reducing Fe content by 2%-3% long-term). Keep away from heat sources (e.g., radiators, boilers).

FAQ
What are ferrous sulfate monohydrate particles? What are the main components and characteristics?
Ferrous Sulphate Monohydrate Granular is an inorganic compound with the chemical formula FeSO₄·H₂O, primarily composed of iron (Fe) and sulfate ions (SO₄²⁻). Key characteristics include:
High iron content (≥30%) and excellent bioavailability;
· Uniform particle size (optional 6-12 mesh, 12-24 mesh, etc.), low dust, easy to store and transport;
· Off-white or light green powder/granules, highly soluble in water with acidic solution;
· Strong stability, less prone to moisture absorption and caking (superior to anhydrous ferrous sulfate).
Is granular monohydrate better than powder for agricultural use?
Precise Application: Granular form has high bulk density (1.2g/cm³), drift rate <2% (vs. >15% for powder), reducing waste;
Deeper Soil Penetration: Granules sink 5-8cm into soil (vs. 1-2cm for powder), slow-release iron increases utilization by 40%;
Machinery Compatibility: Works with seeders/fertilizers directly (powder needs mixing), reducing application time by 50%.
Is monohydrate better absorbed by livestock than other forms?
Higher Bioavailability: Monohydrate’s Fe²⁺ is more easily absorbed (18% absorption rate vs. 12% for anhydrous, 15% for powder);
Gentle on Gastrointestinal Tract: Smooth granule surface (80-120 mesh) reduces friction, lowering diarrhea rate by 25% (vs. powder);
Stable in Acidic Conditions: 95% Fe³⁺ release at pH 3-4 (vs. 80% for anhydrous), preserving feed nutrients.
