Description

Amberlite IRA-400 is a strongly basic anion exchange resin supplied in the chloride form, widely recognized for its high capacity and robust chemical stability. This product is essential for processes requiring the efficient removal or exchange of anions from aqueous and selected organic solutions. It serves critical functions in industries such as water treatment, pharmaceuticals, chemical synthesis, and food & beverage processing, where consistent performance and reliability are paramount.

Application

• Water Purification & Demineralization: Key component in mixed-bed and separate-bed deionization systems for producing high-purity water for power generation, laboratories, and electronics manufacturing.
• Pharmaceutical Purification: Used in the purification of antibiotics, vitamins, and other active pharmaceutical ingredients (APIs), as well as in the preparation of purified water for injection (WFI).
• Chemical Process Catalysis & Separation: Acts as a catalyst or separation agent in organic synthesis, sugar decolorization, and the recovery of precious metals from process streams.
• Food & Beverage Processing: Employed for deashing, decolorization, and the removal of organic acids or impurities in sugar, sweetener, and beverage production.
• Hydrometallurgy: Facilitates the selective recovery and concentration of anions such as nitrate, sulfate, and chromate from mining and metal finishing effluents.
• Condensate Polishing: Used in power plants to remove ionic impurities from steam condensate, protecting turbines and boilers from corrosion and scaling.
