Description

Iron(2+) Sulphate is an inorganic salt of iron in the +2 oxidation state, also known as ferrous sulfate. It is a critical industrial chemical valued for its role as a reducing agent and a source of bioavailable iron. This compound is essential for manufacturers in water treatment, agriculture, and chemical synthesis who require a reliable and consistent source of ferrous ions. Its properties make it a key ingredient in processes ranging from phosphate removal to nutritional supplementation.

Application

• Water and Wastewater Treatment: Acts as a coagulant and reducing agent for phosphate removal, odor control, and sludge conditioning.
• Agricultural and Horticultural Use: Serves as a soil amendment and foliar spray to correct iron chlorosis in plants and as a micronutrient in fertilizers.
• Chemical Manufacturing: Used as a precursor in the production of other iron compounds, pigments (e.g., iron oxide), and as a reducing agent in various chemical synthesis processes.
• Nutritional Supplementation: Employed as a source of iron in animal feed premixes and, in specific high-purity grades, for human nutritional fortification.
• Construction Material: Utilized in cement and concrete production to reduce chromate content and improve durability.
• Textile Industry: Functions as a mordant in dyeing processes to improve color fastness.

Quality Control

Our Iron(2+) Sulphate is produced under a stringent quality management system. Each batch undergoes comprehensive analytical testing to ensure it meets precise specifications for purity, heavy metal content, and other critical parameters. Certificates of Analysis (COA) documenting these results are provided with every shipment to guarantee traceability and compliance with your technical requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area. Due to its hygroscopic and easily oxidized nature, the product should be kept under conditions that minimize exposure to moisture and air. Long-term storage is not recommended; use on a first-in, first-out (FIFO) basis.
