Description

Amberlite Cg-120 is a high-performance, strongly acidic cation exchange resin widely used in purification and separation processes. Its primary value lies in its exceptional capacity and stability for removing cationic impurities from aqueous and non-aqueous streams. This product is essential for industries requiring high-purity water, metal recovery, and catalysis. The material is identified by the CAS registry number 37360-75-1.

Application

• Water Purification & Demineralization: Key component in mixed-bed and polishing units for producing high-purity water for power generation, pharmaceuticals, and microelectronics.
• Chemical Processing & Catalysis: Serves as an acid catalyst in esterification, alkylation, and hydrolysis reactions within fine chemical and petrochemical manufacturing.
• Hydrometallurgy & Metal Recovery: Used for the selective extraction and concentration of valuable metal cations like copper, nickel, and rare earth elements from process streams and leach solutions.
• Sugar & Sweetener Processing: Employed in decolorization and demineralization steps to purify sugar syrups, high-fructose corn syrup, and other sweeteners.
• Pharmaceutical Purification: Facilitates the purification of antibiotics, amino acids, and other active pharmaceutical ingredients (APIs) by removing ionic contaminants.
• Condensate Polishing: Critical in thermal power plants to remove cationic impurities from boiler feedwater and condensate, protecting equipment from corrosion and scaling.
• Analytical Chromatography: Used as a stationary phase in ion-exchange chromatography for the separation and analysis of ionic species in laboratories.
• Wastewater Treatment: Effective for treating industrial effluent by removing heavy metal ions and other cationic pollutants to meet environmental discharge standards.

Quality Control

Our Amberlite Cg-120 is manufactured under a strict quality management system. Each batch undergoes rigorous testing for critical parameters including total exchange capacity, moisture holding capacity, particle size distribution, and uniformity coefficient 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. This product is hygroscopic (moisture-sensitive) and must be stored in a cool, dry, and well-ventilated area at ambient temperature (15-25°C). Ensure the original container is kept sealed when not in use to prevent moisture uptake and contamination. Keep away from incompatible materials such as strong oxidizing agents and strong bases.
