【Abstract】 A novel polyaminated and crosslined chitosan (P CCTS) was prepared by protecting the amino group in chitosan with benzaldehyde and introducing epichlorodydrin and polyethylene polyamine. The structure of P CCTS was determined by FTIR and X ray diffraction. The adsorption properties of P CCTS for Cd(Ⅱ) were studied. The adsorption capacity of P CCTS for Cd(Ⅱ) is much higher than that of chitosan (CTS), and dependant on pH and the concentration of NaCl in solution.更多还原
