对叔丁基酰胺化杯[8]芳烃/聚丙烯腈纳米纤维对Cu2+的吸附性能
Adsorption Capacity of Amide-t-Butylcalix[8] Arene/Polyacrylonitrile Nanofibers for Cu2+
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Cu2+溶液的酸度为pH 4.7，温度为35℃时，该纳米纤维对Cu2+的吸附性能最好。该纳米纤维对Cu2+的吸附既符合Langmuir吸附等温模型，也遵循Freundlich吸附等温模型。

Abstract
Amide-t-butylcalix[8] arene/polyacrylonitrile nanofiber was prepared by electrospinning technique using dimethylformamide as solvent. When the acidity of the Cu2+ containing solution was pH 4.7, and the temperature of the solution was 35℃, the nanofiber showed its best adsorption capacity for Cu2+. The adsorption behavior of the nanofiber toward Cu2+ was found to comply with both the Langmuir adsorption isothermal model and the Freundlich adsorption isothermal model.
