Synthesis and Characterization of PAN/GO/Iron Oxide Composite Nanofibers Membrane for Adsorption of Congo Red Dye from Aqueous Solution

Abstract

In the present study, we have synthesized PAN/GO/ϒ-Fe2O3 composite nanofibers membrane by electrospinning method. Prior to this, first we have synthesized graphene oxide (GO) by advanced Hummer’s method and Maghemite (ϒ-Fe2O3) nanoparticle by sol gel method. These nanoparticles were impregnated with polyacrylonitrile (PAN) solution in DMF solvent and then electrospinning these composite solutions to obtain of PAN/GO/ϒ-Fe2O3 composite nanofibers. The formation, surface morphology and crystalline phase of PAN/GO/ϒ-Fe2O3 composite nanofibers were characterized by FTIR (Fourier Transform Infrared) spectroscopy, FE-SEM (Field emission Scanning Electron Microscope) and XRD (X-Ray Diffraction) analytical techniques. The synthesized PAN/GO/γ-Fe2O3 composite nanofibers have been used as adsorbent materials for the removal of Congo red dyes from the aqueous solution. The batch experiments were carried out for the adsorption studies of Congo Red dyes. The results shows that PAN/GO/ϒ-Fe2O3 fibers are good adsorbents for the removal of Congo red (CR) dyes from aqueous solution
