Article history: Polyacrylonitrile (PAN) nanoﬁbers were obtained by electrospinning technique prior to surface modiﬁca- Received 23 November 2015 tion with polyethylenediaminetetraacetic acid (EDTA) using ethylenediamine (EDA) as the cross-linker. Received in revised form 1 February 2016 The modiﬁed nanoﬁbers (EDTA-EDA-PAN) were subsequently applied in the wastewater treatment for Accepted 2 February 2016 the removal of Cd(II) and Cr(VI). Textural and chemical characterizations of the nanoﬁbers were carried Available online 4 February 2016 out by analysis of the speciﬁc surface area (Brauner Emmet and Teller (BET)) and thermogravimetric anal- yses, scanning electron microscopy and Fourier transform infrared spectroscopy. From the adsorption Keywords: equilibrium studies with Langmuir, Freundlich and Temkin isotherm models, Freundlich was found most Polyacrylonitrile suitable for describing the removal mechanism of the target metals as they collect on a heterogeneously Nanoﬁbers functionalized polymer surface. The EDTA-EDA-PAN nanoﬁbers showed effective sorption afﬁnity for Electrospinning -1 both Cd(II) and Cr(VI), achieving maximum adsorption capacities of 32.68 and 66.24 mg g , respectively, Adsorption Trace metals at 298 K. In furtherance, the nanoﬁbers were regenerated by simple washing with 2 M HCl solution.
