Product Line Description

This is a kind of weakly alkaline anion exchange resin with primary amine, secondary amine, tertiary amine and quaternary amine groups [-NH2, =NH, =N, =N-] in the epoxy chloropropane-polyethylene polyamine copolymer. It can be used as ion exchanger in acidic, neutral and alkaline mediums, with large exchange capacity and speedy exchange ability.It is mainly used in water treatment to remove Cl- and SO2-, removing inorganic acid, extracting organic acid and decolorization when refining the citric acid, streptomycin, malic acid, amino acid etc. And it also can be used in recycling of copper and silver ions.
