Description

Iron Hydroxide is an inorganic compound with the chemical formula Fe(OH)₃, widely recognized for its role as a precursor to iron oxides and as an adsorbent. This compound is valued for its ability to remove contaminants from various process streams, making it a critical material for environmental and industrial purification. Key industries that rely on this product include water treatment, pigments manufacturing, and pharmaceuticals.

Application

• Water Treatment: Acts as a coagulant and adsorbent for removing phosphates, heavy metals, and arsenic from industrial and municipal wastewater.
• Pigments Industry: Serves as a key intermediate in the production of iron oxide pigments (e.g., yellow, red, black) used in paints, coatings, and construction materials.
• Pharmaceuticals: Utilized as an active pharmaceutical ingredient (API) in iron supplements and as a starting material for other iron-based compounds.
• Catalyst Support & Precursor: Used in the synthesis of catalysts for chemical reactions and as a precursor for magnetic materials.
• Gas Purification: Employed as a desulfurizing agent to remove hydrogen sulfide (H₂S) from gas streams.
• Soil Remediation: Applied for immobilizing heavy metals in contaminated soils due to its high surface area and adsorption capacity.

Quality Control

Our Iron Hydroxide is manufactured under a strict quality management system to ensure batch-to-batch consistency and reliability. Each lot is tested against rigorous in-house specifications, which may include parameters for assay, heavy metal content, and loss on drying. A Certificate of Analysis (COA) documenting these results is provided with every shipment. We can supply grades compliant with relevant industrial and reagent standards.

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); therefore, the container must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect product quality and handling properties.
