摘要:通过静电纺丝方法制备了一种含有β-环糊精的聚乙烯吡咯烷酮纳米纤维交联膜(β
-CDXFM),对其进行了红外、X-衍射、SEM 表征,系统研究了该纤维膜对甲基橙的吸附性能,
发现其吸附率达 95%以上。

Abstract: The polyvinylpyrrolidone nanofibrous membranes with β-cyclodextrin glutaraldehyde
crosslinked (β-CDXFM) was prepared by electrospinning membranes were
extensively characterized by various techniques including attenuated total reflectance Fourier
transform infrared spectroscopy (ATR-FTIR), X-ray diffraction (XRD) and scanning electron
microscopy (SEM) to correlate membrane characteristics with their performance. The adsorption
ability of nanofibrous membranes was tested by performing extraction of methyl orange dye from
water. Results of sorption experiments showed that nanofibrous membranes exhibited the
adsorption rate toward Methyl Orange more than 95%.
