摘　　要：以N,N-二甲基甲酰胺为溶剂,采用静电纺丝技术制备了对叔丁基酰胺化杯[8]芳烃/聚丙烯腈纳米纤维。当含Cu^(2+)溶液的酸度为pH 4.7,温度为35℃时,该纳米纤维对Cu^(2+)的吸附性能最好。该纳米纤维对Cu^(2+)的吸附既符合Langmuir吸附等温模型,也遵循Freundlich吸附等温模型。Amide-t-butylcalix[8]arene/polyacrylonitrile nanofiber was prepared by electrospinning technique using dimethylformamide as solvent.When the acidity of the Cu^（2＋）containing solution was pH 4.7,and the temperature of the solution was 35 ℃,the nanofiber showed its best adsorption capacity for Cu^（2＋）.The adsorption behavior of the nanofiber toward Cu^（2＋）was found to comply with both the Langmuir adsorption isothermal model and the Freundlich adsorption isothermal model.
