D315Macroporous Acrylic acid series weakly alkaline anion exchange resin

This product is a kind of anion exchange resin which has polyamine groups in the methyl acrylate-divinylbenzene copolymer, with macroporous structure. This resin has good properties, such as large exchange capacity, small volumn change, strong physical strength, good chemical stability, excellent resistence to contamination and oxidation, speedy exchange capability etc.
It is mainly used in extraction of drugs, alkaline water and radioactive waste water treatment, extraction and decolorization of biochemical substance ,such as citric acid, vitamin C etc, refining and decolorization of sugar solution, removal of inorganic acids, such as Cl-,SO42- etc, extracting molybdenum in hydrometallurgy and water treatment industries.
