| 摘 要： | 通过以壳聚糖为原料,经交联、羟丙基氯化及胺基化,制备了壳聚糖胺基吸附剂。经红外光谱和扫描电镜测定其结构,研究了不同的胺化试剂及其用量对壳聚糖吸附剂胺基含量的影响及对中药液中黄酮化合物的吸附性能。结果表明,改性壳聚糖微球胺基含量比壳聚糖高,对游离黄酮的吸附量随着胺基含量增加而增加。

| Abstract: | A novel aminated chitosan derivative was prepared from chitosan through cross-linking,hydroxylpropyl-chloridization and amination.The effect of different amination agents and the amount of amination agent on the amino group content of the aminated chitosan derivative and the adsorption characteristics for flavones by the aminated chitosan derivative were investigated.The structure of the micorsphere was characterized by scanning electron microscopy(SEM) and Fourier transform infrared spectroscopy(FT-IR).The results indicated that,the properties of the novel aminated chitosan derivative were improved significantly as compared with chitosan. |
