Detailed Product Description for Ferrous Sulfate

What is Ferrous Sulfate?

Ferrous sulfate (also known as iron(II) sulfate) is a highly soluble iron compound commonly used in agriculture, water treatment, pharmaceuticals, and industry. It comes in two common forms:

  • Ferrous Sulfate Monohydrate (FeSO₄·H₂O) – A more concentrated form with higher iron content

  • Ferrous Sulfate Heptahydrate (FeSO₄·7H₂O) – The traditional blue-green crystalline form, used in various applications


Applications of Ferrous Sulfate

📌 Agricultural Industry – Fertilizer & Soil Conditioner

Ferrous sulfate is an essential iron supplement for plant growth and is used in agriculture for:
Correcting Iron Deficiency in Crops – Prevents chlorosis (yellowing leaves) in plants
Soil pH Adjustment – Helps lower alkaline soil pH for optimal nutrient absorption
Micronutrient Fertilizer – Used in compound fertilizers for crops like rice, citrus, and wheat


📌 Water Treatment Industry – Coagulant & Purification Agent

Ferrous sulfate plays a key role in water treatment by:
Removing Phosphates & Heavy Metals – Helps in wastewater treatment
Acting as a Coagulant – Aids in flocculation and sedimentation processes
Reducing Hydrogen Sulfide (H₂S) Odors – Prevents sewage odor formation


📌 Feed & Pharmaceutical Industry – Iron Supplement

Used in Animal FeedBoosts iron levels in livestock and poultry
Pharmaceutical UseTreats iron-deficiency anemia in humans


📌 Industrial Applications

Iron Source in Pigments & Inks – Used in manufacturing of ferric oxide pigments
Cement Industry – Enhances strength and durability of cement
Electroplating & Metal Treatment – Used in steel production and surface treatment
