D111 Macroporous Weak Acid Cation Exchange Resin
D111 This is a kind of cation exchange resin which has carboxylic acid groups [-COOH] in the macroporos acrylic acid-divinylbenzene copolymer. It works with large exchange capacity, speedy exchange ability, small volumn change, good physical strength and chemical stability, excellent capabilities of contamination and oxidation resistance etc.
It is mainly used in extraction of streptomycin, gentamicin, neomycin, lysozyme and other antibiotics, softening and demineralization of industrial use water, removal of heavy metal in waste water, separation and putification of biochemical products, decolorization in sugar industry, removal of ash etc.
