Degradation of Synthetic Reactive Dye Wastewater Based on Amine-Functionalized Polyacrylonitrile Fiber

Abstract:

A series of functional fibers have been prepared by modifying a commercially available polyacrylonitrilefiber (PANF) with polyamines such as ethylenediamine, tetraethylenepentamine and hyperbranched polyethylenimine (HPEI), and then used to coordinate with Fe³⁺, respectively, to produce Fe-modified PAN fiber complexes. The chemical structures of modified PANFs were verified by Fourier transform infrared spectroscopy (FT-IR). X-ray Diffraction (XRD) characterization showed that the inner crystal region of PANF was damaged during the introduction of amine groups.. Organic elemental analysis results to a certain extent demonstrate the success of modification. The coordination of Fe³⁺ was verified by Energy Dispersive Spectroscopy (EDS). The Fe-modified PAN fiber complexes were were used to eliminate the color from synthetic reactive dye wastewater (SRDW, including Reactive Red 195, RR 195) under normal conditions. This study presents a valuable route towards wastewater treatment in dyeing and finishing.
