Description

Amberlite(R) IRA-400 (Cl) is a strongly basic anion exchange resin supplied in the chloride form. This high-capacity, macroreticular resin is engineered for exceptional chemical stability and efficient ion exchange performance across demanding industrial processes. It is a critical component for water purification, chemical processing, and catalysis, serving industries such as pharmaceuticals, power generation, and specialty chemicals where reliable separation and purification are paramount.

Application

• Demineralization & Deionization: Key component in mixed-bed and separate-bed systems for producing high-purity water for laboratories, pharmaceuticals, and power plant boiler feed.
• Chemical Purification: Used to remove acidic impurities and anions from process streams in organic synthesis, sugar refining, and catalyst recovery.
• Catalysis: Serves as a solid-phase catalyst for various alkylation, condensation, and esterification reactions in fine chemical manufacturing.
• Hydrometallurgy: Employed in the recovery and separation of valuable metals like gold, uranium, and tungsten from leach solutions.
• Chromatographic Separation: Acts as a stationary phase for the separation of biological compounds, organic acids, and anions in analytical and preparative chromatography.
• Wastewater Treatment: Effective for removing nitrate, chromate, and other hazardous anions from industrial effluent to meet environmental discharge standards.

Quality Control

Every batch of Amberlite IRA-400 (Cl) is manufactured under a strict quality management system. Our products undergo rigorous testing to ensure consistent performance metrics such as total exchange capacity, moisture holding capacity, particle size distribution, and chemical stability. Certificates of Analysis (COA) detailing these specifications are available upon request to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. This product is hygroscopic (moisture-sensitive). Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Keep the original container sealed to prevent moisture uptake and contamination. Do not allow the resin to freeze or be exposed to extreme heat.
