Description

Iron(II) Sulfate Dihydrate is a vital inorganic salt widely used as a precursor and reducing agent in industrial chemistry. Its primary value lies in its ability to provide bioavailable iron and its utility in water treatment and redox processes. This compound is essential for manufacturers in the agricultural, water purification, and chemical synthesis sectors seeking a reliable source of ferrous ions.

Application

• Water Treatment: Acts as a reducing agent and coagulant for phosphate removal and sludge conditioning in municipal and industrial wastewater plants.
• Agriculture & Horticulture: Serves as a key ingredient in fertilizers and soil amendments to correct iron chlorosis in crops and turfgrass.
• Chemical Manufacturing: Used as a precursor for the synthesis of other iron compounds, pigments (e.g., iron oxide), and as a reducing agent in various chemical processes.
• Nutritional Supplement: Employed in the production of animal feed premixes to prevent and treat iron deficiency.
• Laboratory & Research: Functions as a standard or reagent in analytical chemistry and educational experiments.

Quality Control

Our Iron(II) Sulfate Dihydrate is produced under a stringent quality management system. Each batch undergoes rigorous testing to ensure it meets precise specifications for purity, heavy metal content, and physical properties. Certificates of Analysis (COA) documenting these results are available upon request to support your quality assurance protocols.

Storage

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