| Abstract: | PurposeTo prepare a series of chitosans with different molecular weight and to study the physical and chemical properties of the chitosans.MethodsA series of chitosans with different molecular weights were prepared by oxidation with hydrogen peroxide in distilled water. The resulting products were characterized by IR spectra and thermogravimetrically.ResultsThe optimal conditions for preparing different molecular weight chitosans were obtained in the experiment.ConclusionThe structure of chitosan was not evidently changed after the degradation of chitosan by hydrogen peroxide and the stability of chitosan was increased with decreasing the molecular weight of chitosan. |
