Polyacrylonitrile (PAN) nanofibers have been fabricated via electrospinning technique. Then an aminated chelating PAN nanofiber (APAN nfs) with high adsorption capacity for copper and dichromate ions have been prepared by a one-step reaction between the PAN nanofibers and diethylenetriamine (DETA). The morphology, structure of the as-prepared chelating nanofibers are characterized by scanning electron microscopy (SEM), FT-IR spectroscopy, respectively. The as-prepared chelating nanofibers show high metal removal properties, such as the maximum removal capacity of copper ion is 137.83 mg/g and dichromate ions are 156.25 mg/g. The adsorption mechanism of copper and dichromate ions have also been discussed in this work.

Keywords:polymer chemistry and physics; PAN; nanofiber; electrospinning; heavy metal ion
