Description

Amberlite IR-120 is a strongly acidic, gel-type cation exchange resin supplied in the sodium form, widely recognized for its high capacity and stability. This robust resin is essential for critical industrial processes requiring the selective removal or exchange of cations from aqueous and non-aqueous streams. It serves as a fundamental component in water treatment, chemical purification, catalysis, and hydrometallurgy, providing reliable performance for global manufacturers and processors.

Application

• Industrial Water Softening & Demineralization: Primary workhorse for removing calcium, magnesium, and other scale-forming cations from boiler feed water, process water, and ultrapure water systems.
• Chemical & Pharmaceutical Purification: Used for decolorization, removal of metal ion catalysts, and purification of intermediates, sugars, and organic compounds.
• Catalysis: Serves as a solid acid catalyst in organic synthesis reactions such as esterification, alkylation, and hydrolysis, offering easy separation and reusability.
• Hydrometallurgy & Metal Recovery: Critical for the selective recovery and concentration of valuable metals like copper, nickel, and rare earth elements from leach solutions.
• Sugar & Sweetener Processing: Employed in decolorization and demineralization steps to refine sugar syrups and high-fructose corn syrup.
• Condensate Polishing: Used in power plants to remove cationic impurities from steam condensate, protecting turbines and boilers from corrosion.

Quality Control

Our Amberlite IR-120 is manufactured under a strict quality management system to ensure batch-to-batch consistency and performance reliability. Each lot is tested against key physical and chemical parameters, including total exchange capacity, moisture holding capacity, bead size distribution, and ionic form. 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, well-ventilated area at ambient temperature (15-25°C). Keep the resin moist and avoid freezing or exposure to extreme heat. Isolate from strong oxidizing agents.
