Preparation of a Cyclomaltoheptaose （p—cyclodextrin） Cross—linked Chitosan Derivative via Glyoxal or Glutaraldehyde
摘要
A cyclomaltohcptaose-β-cyclodextrin (β-CD) crosslinked chitosan derivative via glyoxal or glutaraldehyde was prepared. The structures of β-CD crosslined chitosan with glyoxal or glutaraldehyde were characterized by IR spectra. The surface morphology of the β-CD crosslinked chitosan particles was examined using a scanning electron microscope. The immobilization capacity of β-CD on chitosan was affected on the weight ratio of β-CD/chitosan,the utilization amount of crosslinking agent, the acidity of the reaction system and the temperature.The adsorption for nicotine indicated that the chitosan-β-CD was a good adsorbent.
