Description

Iminodiacetic Acid Resin is a specialized chelating ion exchange resin, widely recognized for its high selectivity for transition and heavy metal ions. This functionalized polymer is critical for purification and separation processes where precise metal ion removal is required. It serves as an essential material for industries including water treatment, hydrometallurgy, pharmaceuticals, and analytical chemistry.

Application

• Metal Ion Removal & Water Purification: Selective extraction of heavy metals like lead, copper, nickel, and cadmium from industrial wastewater and drinking water.
• Hydrometallurgy & Metal Recovery: Concentration and recovery of valuable metals such as gold, silver, and rare earth elements from leach solutions.
• Pharmaceutical Purification: Used in the purification processes of active pharmaceutical ingredients (APIs) to remove trace metal catalysts and impurities.
• Analytical Chemistry & Chromatography: Serves as a stationary phase in chelation chromatography for the separation and preconcentration of metal ions prior to analysis (e.g., ICP-MS, AAS).
• Catalyst Support: Functional support for immobilizing metal catalysts in various organic synthesis reactions.
• Nuclear Industry: Separation and recovery of specific radionuclides from nuclear waste streams.

Quality Control

Our Iminodiacetic Acid Resin is manufactured under a strict quality management system. Each batch is tested for critical parameters including chelating capacity, particle size distribution, moisture content, and functional group density to ensure consistent performance. 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, and well-ventilated area at room temperature (15-25°C). Keep away from strong oxidizing agents. The resin is supplied in a moist state; avoid letting the material dry out completely, as this may affect performance characteristics.
