| Abstract: | The preparation and characterization of dimethylamine modified glutaraldehyde- crosslinked chitosan resin activated with cyanuric chloride, and its infrared spectra properties were studied. The adsorption capacities of the modified crosslinked chitosan resin to copper(II) and bovine serum albumin(BSA) were 42mgg-1(dry resin) and 940mgg-1(dry resin), respectively. The adsorptions were correlated by the Freundlich isotherm equation. The resin has good mechanical strength, and can be used for the separation and purification of metal ions and proteins. |
