Description

Duolite A 340 Ion-Exchange Resin is a high-performance, strongly basic anion exchange resin designed for demanding industrial separation and purification processes. Its robust structure and consistent exchange capacity make it a critical component for ensuring product purity and process efficiency. This resin is essential for industries requiring the removal of anions, organic acids, or color bodies from process streams, including water treatment, chemical manufacturing, and sugar refining.

Application

• Water Demineralization & Purification: Used in mixed-bed or separate-bed systems for the production of high-purity deionized (DI) water for power plants, laboratories, and electronics manufacturing.
• Sugar & Sweetener Decolorization: Effectively removes colorants and organic impurities (like anions and organic acids) during the refining of cane sugar, beet sugar, and high-fructose corn syrup.
• Chemical Process Catalysis & Separation: Serves as a catalyst or purification medium in various organic synthesis reactions and for the recovery of valuable anions from chemical process liquors.
• Wastewater Treatment: Employed for the selective removal of hazardous anions such as nitrate, chromate, and perchlorate from industrial effluent streams.
• Pharmaceutical Intermediates Purification: Used to purify process streams and isolate intermediates by removing acidic impurities and ionic contaminants.
• Condensate Polishing: Applied in power generation to remove ionic contaminants from steam condensate, protecting boilers and turbines from corrosion.

Quality Control

Our Duolite A 340 Ion-Exchange Resin is manufactured under a strict quality management system. Every batch undergoes rigorous testing for key parameters including total exchange capacity, moisture content, particle size distribution, and ionic form to ensure consistent performance and reliability. Certificates of Analysis (COA) documenting these specifications are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at ambient temperature (15-25°C). This product is hygroscopic (moisture-sensitive); ensure containers are sealed after use to prevent moisture uptake, which can affect performance. Keep away from incompatible materials such as strong oxidizing agents.
