辐射降解法制备低聚水溶性壳聚糖之三:产品分析评价研究
Preparation of water-soluble oligochitosan by radiation degradation (3) :characterization of oligochitosan by instrument analysis
【摘要】 采用元素分析法、红外光谱法和X射线衍射法对制备的辐解低聚壳聚糖和外购的酶解低聚壳聚糖进行了分析,发现采用液态辐解法所制备寡糖样品的氮元素含量和脱乙酰度与原料相比都有明显增加。
【Abstract】 The use of element analysis、infrared spectroscopy and x-ray diffraction for characterization of oligochitosan are examined,it was found that,comparing with raw material,both the degree of deacetylation and nitrogen content of oligochitosan prepared by radiation degradation were remarkably increased.
