Abstract

In this research, chitosan coated Fe3O4 as a new adsorbent for the removal of furfural from aqueous solutions was successfully synthesized. The adsorbent was characterized by Fourier transform infrared spectrometry (FTIR), X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM) and energy dispersive spectrometry (EDS). These results indicate that the Fe3O4 is coated with chitosan successfully. In order to find the optimum adsorption conditions, a series of batch adsorption experiments were performed. As a result, the maximum adsorption capability (121.7 mg gāˆ’1) was obtained at pH = 8, rotational speed = 200 rpm, contact time = 5 h. Moreover, the adsorption kinetics of furfural by adsorbent were examined and the kinetic data indicates that the adsorption process could be well described by the Freundlich isotherm model.
