摘　　要：应用静电纺丝技术制备α-环糊精(α-CD)/聚丙烯腈(PAN)纤维膜,采用SEM、FT-IR分别对纳米纤维膜进行表征。通过考察pH值、吸附时间、重金属离子初始浓度、温度几个因素,系统研究了α-CD/PAN纤维膜对重金属离子的吸附影响。结果表明:在溶液pH=6,吸附时间为2h,重金属离子初始浓度为10mg/L,温度为35℃的条件下,纳米纤维膜对铜离子(Cu^(2+))、锌离子(Zn^(2+))、镍离子(Ni^(2+))和铅离子(Pb^(2+))的吸附达到最佳,吸附容量分别为9.11、9.02、9.31和8.87mg/g。α-CD/PAN nanofiber membrane was prepared by electrospining,and characterized by scanning electron microscope（SEM）and fourier transform infrared（FT-IR）.The adsorption properities ofα-CD/PAN nanofiber membrane for heavy metal ions in water were systematically studied,and the affection of pH value,adsorption time,initial concentration of heavy metal ions and temperature on adsorption properties were investigated.The adsorption capacities of Cu^（2＋）,Zn^（2＋）,Ni^（2＋） and Pb^（2＋） by α-CD/PAN were 9.11mg/g,9.02mg/g,9.31mg/g and 8.87mg/g,at pH=6,adsorption time of 2hours,the initial heavy metal ions of 10mg/L,and temperature of 35℃.
