A narrow distribution low molecular weight chitosan(LMWCTS) was prepared by the oxide degradation system adjusted with trace amount of zinc sulfate.Fluorescence probe was used to investigate the polarity of micro-area of this degradation system,IR and GPC were utilized for measuring the physic-chemical properties of these LMWCTS samples.The system with 3.8 mmol ZnSO₄ had a narrow distribution of LMWCTS (M_w=973,d=1.1) and the yield of LMWCTS was 85%.Those primary structure units of the chitosan have not been altered after degradation.
- low molecular weight chitosan,
- oxide degradation,
- polarity of micro-area
