Description

Dowex 2X8-100 Ion-Exchange Resin is a strongly basic, Type 2 anion exchange resin supplied in the chloride form, known for its high capacity and robust physical stability. This product is engineered for efficient removal of anions, including nitrates, sulfates, and organic acids, from aqueous streams across demanding industrial processes. It is an essential component for water treatment, chemical purification, and hydrometallurgical applications, serving industries such as power generation, pharmaceuticals, and metal recovery.

Application

• Demineralization & Deionization: Key component in mixed-bed or separate-bed systems for producing high-purity water for laboratories, pharmaceuticals, and high-pressure boilers.
• Nitrate & Sulfate Removal: Effective in treating drinking water and process water to meet regulatory and quality standards by selectively removing problematic anions.
• Chemical & Sugar Processing: Used for decolorization, deashing, and purification of organic acids, sugars, and other chemical intermediates.
• Hydrometallurgy: Facilitates the recovery and separation of valuable metals like uranium, tungsten, and molybdenum from process leach solutions.
• Condensate Polishing: Removes ionic impurities from power plant steam condensate to protect turbines and boilers from corrosion and scaling.
• Wastewater Treatment: Employed to remove anionic contaminants, including chromates and arsenates, from industrial effluent streams.

Quality Control

Our Dowex 2X8-100 resin is manufactured under strict quality protocols to ensure batch-to-batch consistency and performance reliability. Each lot is tested for critical parameters including total exchange capacity, moisture content, bead size distribution, and physical integrity. Certificates of Analysis (COA) detailing these specifications are available upon request to support your quality assurance and regulatory needs.

Storage

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