The preparation of chelating nanofibers of polyacrylonitrile and the study of its adsorptive behiviour

Modified polyacrylonitrile(PAN) nanofiber is prepared through reaction of hydroxylamine on PAN nanofiber prepared by electrospinning and nitrile group changed into amid-oxime group.The adsorptivity of modified PAN nanofibers on lead ion is investigated.The result shows that the modified PAN nanofibers exhibite high adsorptivity on lead ion.
