Description

Fe(III)-EDTA is a stable, water-soluble chelate complex of iron (III) and ethylenediaminetetraacetic acid. This compound is critically important for providing bioavailable iron in systems where standard iron salts would precipitate or become unavailable. It is essential for industries requiring precise iron delivery and sequestration, particularly in agriculture, water treatment, and various chemical processes.

Application

• Agricultural Micronutrient Fertilizer: Used in foliar sprays and hydroponic nutrient solutions to correct iron chlorosis in plants, especially in high-pH soils.
• Water Treatment & Chelant: Acts as a sequestrant to control metal ions (like calcium and magnesium) in boiler and cooling water systems to prevent scale formation.
• Chemical Synthesis & Catalyst: Serves as a catalyst or reagent in oxidation reactions and organic synthesis due to its redox-active iron center.
• Pulp & Paper Industry: Utilized in bleaching processes, such as hydrogen peroxide stabilization, to improve efficiency and pulp brightness.
• Photographic Development: Employed in certain photographic developing solutions as an iron-based oxidizing agent.
• Laboratory & Research: Used as a standard or reagent in analytical chemistry and biochemical research involving iron metabolism.
• Soil Remediation: Applied in chelate-enhanced phytoremediation to mobilize heavy metals for plant uptake and soil cleanup.
