Description

Ferrous Sulfate Hexahydrate is a hydrated inorganic salt of iron, widely recognized for its role as a versatile reducing agent and essential iron source. Its commercial importance stems from its high solubility and bioavailability, making it a critical raw material across multiple industrial and nutritional sectors. Key industries that rely on this compound include water treatment, agriculture, animal nutrition, and pharmaceutical manufacturing, where consistent quality and reliable supply are paramount.

Application

• Water & Wastewater Treatment: Acts as a highly effective coagulant and reducing agent for phosphate removal and odor control in municipal and industrial water systems.
• Agricultural & Horticultural Use: Serves as a vital soil amendment and foliar spray to correct iron chlorosis (yellowing) in crops, promoting healthy plant growth.
• Animal Feed & Nutrition: Utilized as a nutritional iron supplement in premixes to prevent anemia and support overall animal health in livestock and poultry.
• Chemical Manufacturing & Synthesis: Employed as a precursor and reducing agent in the production of other iron compounds, pigments (iron oxide), and catalysts.
• Pharmaceutical & Dietary Supplements: Used in the formulation of iron supplements and fortification products to address human nutritional iron deficiencies.
• Cement & Construction: Functions as a chromate reducer and conditioning agent to enhance the properties and durability of cement mixtures.

Quality Control

Our Ferrous Sulfate Hexahydrate is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure it meets precise specifications for purity, heavy metal content, and physical properties. Certificates of Analysis (COA) are provided and can be tailored to meet specific customer or regulatory requirements, including those for feed and technical grades.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and easily oxidized; prolonged exposure to air and moisture must be avoided to prevent caking and oxidation. Keep away from strong oxidizing agents.
