摘　　要：高的孔隙率和比表面积对纳米纤维而言是影响吸附效果的主要因素,而β-环糊精/聚丙烯腈纳米纤维由于环糊精的包络特性,可以很大程度地增强纤维的吸附能力。探讨了纳米纤维对有机小分子的吸附动力学。根据吸附时间不同、吸附初始浓度不同,还有含有不同质量分数环糊精的纳米纤维的吸附情况,系统研究了纳米纤维吸附能力的大小。研究结果表明,环糊精可以增强纤维对中性红的吸附能力,β-环糊精/聚丙烯腈纳米纤维是一种具有应用潜力的小分子有机物吸附材料。High porosity and specific surface area are the main factors affecting the adsorption effect of nano-fibers.β-cyclodextrin/polyacrylonitrile nanofiber can enhance the adsorption capacity of the fibers to a great extent due to the encapsulation properties of cyclodextrins.The adsorption kinetics of organic small molecules by nanofibers was explored.The extent of the adsorption capacity of the nanofibers was systemati-cally studied based on different adsorption times,different initial concentrations of adsorption,and nanofi-bers containing different mass fractions of cyclodextrins.The results indicate that cyclodextrin can enhance the adsorption capacity of fiber on neutral red,thusβ-cyclodextrin/polyacrylonitrile nanofiber has great po-tentials to adsorb small-molecule organic material.
