Ferrous Sulfate Heptahydrate Powder FeSO4·7H2O 7782-63-0 for Industrial Water Treatment and Agriculture

Ferrous sulfate heptahydrate powder is an inorganic compound with chemical formula FeSO₄·7H₂O. This versatile industrial chemical is primarily used in water purification, iron salt production, ink manufacturing, magnetic iron oxide creation, and as a disinfectant and catalyst. It serves as an essential component in various industrial processes including coal dyeing, tanning, bleaching, wood preservation, and compound fertilizer additives.

• Water Treatment: Used for flocculation purification and phosphate removal from municipal and industrial effluents to prevent eutrophication of water bodies
• Restorative Agent: Primarily employed to restore chromate in cement applications
• Colorant Production: Essential for manufacturing iron tannate inks and other ink formulations; used in wood dyeing mordants and concrete coloring
• Agricultural Use: Regulates soil pH, promotes chlorophyll composition as iron fertilizer, and prevents yellowing in plants; also functions as pesticide for crop disease prevention
• Analytical Chemistry: Serves as chromatographic analysis reagent in laboratory settings

• Dissolve using acidic solvent with pH value less than 5; avoid direct use of alkaline water
• Prevent sediment from wrapping roots or covering leaves; recommended to use after dilution
• Do not use simultaneously with compound fertilizer; apply half a month after each compound fertilizer application

• Store sealed to avoid contact with air, moisture, and rain
• Keep in cool, ventilated area away from fire, heat sources, and direct sunlight
• Store separately from oxidizers, alkalis, and edible chemical raw materials
• Package in polyethylene plastic film bags (minimum 0.05mm thickness) with outer plastic woven bags for optimal sealing
• Storage area should contain appropriate leak containment materials with clear warning signs and firefighting equipment
