PREPARATION OF CROSSLINKED CHITOSAN RESINS SUITABLE FOR PROTEIN ADSORPTION

Crosslinked chitosan resins were synthesized by two methods.Compared with conventional preparation,adding porogenic agents at the course of synthesis can enhance the adsorption ability of resin toward protein,while the mechanical strength is rather low.A good strength and large porosity chitosan resin was obtained by crosslinking it with epichlorohydrin.The experimental results indicated that this kind of resin posessed good capacity for both copper ion and protein.
