摘要:
采用本体聚合法,以壳聚糖(CTS)为基材,L-甲硫氨酸为印迹分子,聚乙二醇(PEG)2000、戊二醛为交联剂,制备了L-甲硫氨酸-戊二醛-聚乙二醇-壳聚糖分子印迹复合膜.实验结果表明:合成的L-甲硫氨酸-戊二醛-PEG-壳聚糖分子印迹复合膜的溶胀性和膜清水通量较好,对氨基酸的渗透量为0.130 mmol·cm-2和L,D-甲硫氨酸的分离因子为1.76.FT-IR、 SEM 、XRD和TGA表征分析显示:分子印迹膜表面平整、微观结构规整紧密,具有较低的结晶度和高热稳定性.
Abstract:
L-methionine-glutaraldehyde-polyethylene glycol(PEG)-chitosan molecularly imprinted membrane are prepared by ontology polymerization with chitosan(CTS)as the backing material,L-methionine as imprinting molecule,and polyethylene glycol(PEG)2000,glutaraldehyde as crosslinking agent.The experimental results show that the swelling and water flux of chitosan composite membrane are good,the permeation capacity of L-methionine is reached by 0.130 mmol·cm-2,and separation factor of L,D-methionine is 1.76.The molecularly imprinted composite membrane,which is characterized by FT-IR,SEM,XRD and TGA,has compact microstructure,low crystallinity and high thermal stability.
