Abstract

In this work, ferric oxide nanoparticle decorated carbon fibers and carbon nanotubes (CNF/Fe<inf>2</inf>O<inf>3</inf> and CNT/Fe<inf>2</inf>O<inf>3</inf>) were synthesized and characterized by scanning electron microscopy (SEM), thermogravimetric analysis (TGA), energy dispersive X-ray spectroscopy (EDS), transmission electron microscopy (TEM), X-ray diffraction (XRD), zeta potential and BET surface area analyzer. The prepared nanocomposites were evaluated or the removal of phenol ions from aqueous solution. The effects of experimental parameters, such as shaking speed, pH, contact time, adsorbent dosage and initial concentration, were evaluated for the phenol removal efficiency. The adsorption experimental data were represented by both the Langmuir and Freundlich isotherm models. The Langmuir isotherm model best fitted the data on the adsorption of phenol, with a high correlation coefficient. The adsorption capacities, as determined by the Langmuir isotherm model were 0.842, 1.098, 1.684 and 2.778mg/g for raw CNFs, raw CNTs, CNF-Fe<inf>2</inf>O<inf>3</inf> and CNT-Fe<inf>2</inf>O<inf>3</inf>, respectively.
