Description

Royer(R) Anion Exchange Resin CAS NO 69011-15-0 is a high-performance, strongly basic anion exchange resin designed for the selective removal of negatively charged ions from aqueous and non-aqueous solutions. Its robust polymeric matrix and functional groups provide exceptional capacity, stability, and regeneration efficiency, which are critical for maintaining process purity and operational cost-effectiveness. This resin is essential for industries requiring high-purity water, metal recovery, or the purification of process streams, including power generation, pharmaceuticals, chemical manufacturing, and hydrometallurgy.

Application

• Ultrapure Water Production: Key component in mixed-bed and polishing demineralization systems for power plants, microelectronics, and high-purity boiler feed water.
• Pharmaceutical Purification: Used in the purification of active pharmaceutical ingredients (APIs), antibiotics, and sugars by removing acidic impurities and color bodies.
• Chemical Process Stream Treatment: Effective for the removal of acids, organic anions, and catalysts from reaction mixtures in fine chemical and petrochemical synthesis.
• Hydrometallurgy & Metal Recovery: Selective adsorption and concentration of valuable anionic metal complexes, such as gold cyanide or platinum group metals, from leach solutions.
• Sugar & Sweetener Decolorization: Employed in the decolorization and deashing of sugar syrups, corn sweeteners, and amino acid solutions.
• Nitrate & Perchlorate Removal: Critical for treating contaminated groundwater and drinking water to meet regulatory standards for nitrate and perchlorate levels.
• Condensate Polishing: Protects steam systems and turbines by removing corrosive anions from condensate in industrial and thermal power plants.
• Catalyst & Solvent Recovery: Facilitates the recovery and recycling of homogeneous catalysts and purification of industrial solvents.

Quality Control

Our Royer(R) Anion Exchange Resin is manufactured under a strict quality management system. Each batch is tested against rigorous internal specifications to ensure consistent performance in capacity, kinetics, and physical stability. While not typically certified to pharmacopeial monographs, production can adhere to cGMP principles for sensitive applications. A comprehensive Certificate of Analysis (COA) detailing moisture content, ion exchange capacity, bead size distribution, and functional group integrity is provided with every shipment.

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). The resin is supplied in a moist state and must not be allowed to freeze or dry out, as this can cause irreversible physical damage to the polymer matrix. Keep away from strong oxidizing agents.
