壳聚糖固载化环糊精的制备和表征

Preparation Characterization of Chitosan Immobilized β-Cyclodextrin

以戊二醛为交联剂制备壳聚糖和环糊精包合物β-CD-CTS,通过不同的投料比,测试出β-CD-CTS中β-CD的固载量,根据傅里叶红外光谱仪显示制备的β-CD-CTS包合物中β-CD已经交联在CTS上,不是简单的物理吸附。探讨戊二醛交联剂的添加量对β-CD-CTS包合物微观结构的影响。

β-CD-CTS cross-linking inclusion compound material was prepared by using glutaraldehyde as cross-linking agent,measure the loading contents ofβ-CD in different reactant ratio.The inclusion ofβ-CD in the preparedβ-CD-CTS complex has been cross-linked to the CTS according to the Fourier infrared spectrometer,other than Physical Process.The effect of the amount of glutaraldehyde crosslinking agent on the microstructure ofβ-CD-CTS inclusion compound was investigated.
