D315 Macroporous Acrylic Acid Series Weak Alkaline Anion Exchange Resin
About this Product:
This is a macroporous anion exchange resin composed of a methyl acrylate-divinylbenzene copolymer. It features polyamine functional groups and is engineered for superior performance.
This resin’s key attributes include:
Speedy Exchange Capability: Facilitates rapid and effective ion exchange.
Large Exchange Capacity: Efficiently removes a high volume of ions.
Minimal Volume Change: Ensures physical stability throughout service cycles.
Exceptional Durability: Boasts strong physical strength and excellent resistance to chemical degradation, contamination, and oxidation.
Application
This anion exchange resin is a highly versatile solution with a wide range of applications, including:
Hydrometallurgy: Employed in the extraction of metals, such as molybdenum.
Pharmaceuticals & Biotechnology: Used for the extraction of drugs and the extraction and decolorization of biochemical substances, such as citric acid and Vitamin C.
Water Treatment: Effective in treating alkaline and radioactive wastewater, and for removing inorganic acids like chloride (Cl−) and sulfate (SO42−) in general water treatment processes.
Food & Beverage: Instrumental in the refining and decolorization of sugar solutions.
