摘要
采用电子束辐照降解壳聚糖,并利用体积排阻色谱-十八角度激光光散射仪、环境扫描电子显微镜、FTIR光谱仪、X衍射仪对辐照样品进行分析。结果表明:随着辐照剂量的增加,壳聚糖的分子量逐渐降低;颗粒随着辐照剂量的增加而逐渐减小;在5～300kGy的辐照剂量范围内,电子束辐照对其结构、脱乙酰度和结晶度几乎没有影响。
The Chitosan samples irradiated by electron beam were analyzed using size exclusion chromatography-18 angle laser light scattering instrument,the environmental scanning electron microscope,FTIR spectrometer and X-ray diffractometer.The results showed that,with the increasinge of irradiation dose,chitosan＇s molecular weight reduced and particles size gradually decreased.In the range of 5 to 300kGy,electron beam irradiation has less effect on structure,deacetylation degree and crystallinity of chitosan.
