Abstract

hemical coprecipitation method. The characterization of Fe3O4−
MWCNTs adsorbent was carried out using X-Ray
diffraction (XRD); Fourier transform infrared spectroscopy (FTIR); Brunauer-Emmett-Teller (BET) and scanning electron
microscopy (SEM). The prepared material has exhibited a higher adsorption capacity 296.52 mg.g-1 to remove the
Bromocresol purple (BCP) dye from aqueous solutions. Kinetic study shows that the equilibrium time reached after 80
minutes and the pseudo second order best suited this adsorption. Isotherm models indicate that the adsorption represented
perfectly by the Langmuir. Thermodynamic study suggests that the sorption process is spontaneous, exothermic and
physisorption type. This work focused on the efficiency of nanocomposite Fe3O4−
MWCNTs as a magnetically separable
adsorbent compared with pure multi-walled carbon nanotubes
