Description

Amberlite(R) Irc-748 is a high-capacity, chelating ion exchange resin specifically designed for the selective removal of heavy metal ions from aqueous solutions. Its core value lies in its exceptional selectivity for cations like copper, nickel, and lead, even in the presence of high concentrations of alkali and alkaline earth metals. This product is essential for industries requiring ultrapure process water, efficient metal recovery, or stringent wastewater treatment, such as microelectronics, metal finishing, hydrometallurgy, and chemical manufacturing.

Application

• Ultrapure water production for the microelectronics and power generation industries.
• Selective recovery and concentration of valuable metals (copper, nickel, cobalt) in hydrometallurgical processes.
• Heavy metal removal from industrial wastewater to meet environmental discharge regulations.
• Polishing step in chemical process streams to remove trace metal contaminants.
• Catalyst protection in various chemical syntheses by scavenging metal impurities.
• Treatment of condensate and feedwater in steam systems to prevent corrosion.
• Laboratory-scale purification and analytical sample preparation.

Quality Control

Our Amberlite(R) Irc-748 is manufactured under a rigorous quality management system. Each batch is tested to ensure consistent performance characteristics such as total capacity, selectivity, kinetics, and physical stability. A comprehensive Certificate of Analysis (COA) detailing these parameters is provided with every shipment to guarantee product integrity and traceability for our global B2B clients.

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). Keep away from strong oxidizing agents. The resin is supplied in a moist state and should not be allowed to dry out, as this may affect its performance characteristics.
