Description

Amberlite Strongly Acidic Cation Exchanger CAS NO 39464-90-9 is a high-performance, macroreticular, sulfonated polystyrene-divinylbenzene resin designed for industrial-scale ion exchange processes. Its robust cross-linked structure provides exceptional chemical stability, high exchange capacity, and excellent physical durability, making it a critical component for reliable and efficient purification and separation. This product is essential for industries requiring the removal, recovery, or concentration of cationic species from aqueous and non-aqueous streams.

Application

• Water Treatment & Demineralization: Primary application in producing high-purity deionized (DI) water for power generation, microelectronics, and high-pressure boiler feed.
• Chemical Processing & Catalysis: Used as a solid acid catalyst in organic synthesis reactions such as esterification, alkylation, and hydrolysis.
• Sugar & Sweetener Refining: Decolorization and demineralization of sugar syrups, corn sweeteners, and other carbohydrate solutions.
• Pharmaceutical Purification: Isolation and purification of antibiotics, amino acids, and other pharmaceutical intermediates.
• Hydrometallurgy & Metal Recovery: Selective recovery of valuable or toxic metal cations (e.g., copper, nickel, zinc) from mining leachates and industrial waste streams.
• Food & Beverage Processing: Water softening, dealkalization, and stabilization in beverage production and food ingredient manufacturing.
• Nuclear Industry: Treatment of low-level radioactive liquid waste for the removal of fission products.
• Chemical Separation: Chromatographic separation of mixtures in analytical and preparative-scale applications.

Quality Control

Our Amberlite Strongly Acidic Cation Exchanger is manufactured under a strict quality management system. Each batch undergoes rigorous testing to ensure it meets critical performance parameters such as total exchange capacity, moisture holding capacity, particle size distribution, and uniformity coefficient. Certificates of Analysis (COA) documenting these specifications are available upon request. Our production adheres to relevant ISO standards, and the resin is suitable for use in applications requiring compliance with FDA, USP, and other global regulatory frameworks for indirect food contact and pharmaceutical processing.

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 completely, as this can cause irreversible physical damage to the bead structure. Keep away from strong oxidizing agents.
