Study on the Molecular Weight and the Distribution of Chitosan in its Oxidative Degradation Process by GPC

摘要: 用凝胶渗透色谱法跟踪研究了过氧化氢对壳聚糖氧化降解过程中壳聚糖的分子量及其分布的影响，结果表明，反应温度、时间和过氧化氢用量对壳聚糖的降解程度及降解产品质量均有影响。

Abstract: The molecular weight and the distribution of chitosan in the oxidative degradation process with hydrogen peroxide as oxidant was tracked by GPC. The results show that the degradation degree and quality of degraded chitosan were affected by reaction temper
