Description

Ferrous Sulfate is an essential inorganic salt, widely recognized for its role as a versatile reducing agent and a vital source of bioavailable iron. Its significance lies in its ability to address iron deficiency across multiple industrial and nutritional sectors, ensuring process efficiency and product fortification. This compound is a critical raw material for manufacturers in water treatment, agriculture, animal nutrition, and the pharmaceutical industry, where consistent quality and reliable supply are paramount.

Application

• Water & Wastewater Treatment: Acts as a reducing agent and coagulant for phosphate removal and sludge conditioning.
• Agricultural & Horticultural Use: Serves as a soil amendment and fertilizer to correct iron chlorosis in plants.
• Animal Feed Supplement: An essential nutritional additive to prevent iron deficiency anemia in livestock and poultry.
• Pharmaceutical & Nutritional Industries: Used as an iron source in hematinic preparations and food fortification.
• Chemical Manufacturing: A precursor in the production of other iron compounds, pigments (e.g., iron oxide), and as a reducing agent in chemical synthesis.
• Cement & Construction: Employed as a reducing agent to minimize chromium (VI) content in cement.

Quality Control

Our Ferrous Sulfate is manufactured under a stringent quality management system. We offer various grades, including Technical, Feed, and USP/Pharmaceutical grades, each produced to meet specific industry requirements. Every batch is tested for critical parameters such as assay, heavy metal content, and insoluble matter. Certificates of Analysis (COA) are provided to ensure traceability and compliance with relevant specifications, including FCC, USP, or customer-defined standards.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area. Due to its hygroscopic (moisture-sensitive) and easily oxidized nature, the product should be kept away from oxidizing agents and stored under conditions that minimize exposure to air and moisture to prevent caking and oxidation. Recommended storage temperature is 15-25°C.
