Features
- Effective Reducing Agent: Functions as a dependable weak reducing agent, making it highly valuable in chemical processes such as the reduction of chromate in cement and the precipitation of metallic gold during refining.
- High Iron Bioavailability: Serves as a highly accessible source of iron, making it an excellent nutritional supplement and fortifier for human, animal, and plant biological uptake.
- High Aqueous Solubility: Easily dissolves in water, allowing for seamless integration into liquid-dosage treatments, agricultural sprays, and large-scale water treatment facilities.
- Versatile Chemical Precursor: Acts as a reactive intermediate in the synthesis of various iron compounds, including iron oxide pigments, ferrites, and poly iron sulfate.
Applications
- Agriculture & Animal Feed: Applied as a fertilizer and soil conditioner to treat iron chlorosis (iron deficiency) in horticulture. It also acts as a pesticide and iron fortifier in feed additives.
- Food & Pharmaceuticals: Used as a regulated nutritional iron fortifier and coloring agent in cereals, dairy, sweets, and beverages. Medically, it is administered to treat iron-deficiency anemia.
- Water & Sewage Treatment: Deployed in industrial and municipal water treatment plants as a water purifier and coagulant, specifically utilized to remove phosphates.
- Industrial Manufacturing: Utilized as a mordant in wool dyeing and wood processing. It is also a key raw material in the manufacture of inks, lithography, leather dyes, and as a polymerization catalyst.
