Abstract

Magnetite/carbon nanocomposites, prepared by a simple combustion synthesis technique, were tested for the removal of phenol and of some phenol derivatives: p-chlorophenol (p-CP), 3-aminophenol (3-AP), p-nitrophenol (p-NP), 2,6-dimethylphenol (DMP) and 2,4,6- trimethylphenol (TMP) from aqueous solutions. The effect of different parameters, including the magnetite/carbon ratio, initial concentration of pollutant and the contact time on the removal efficiency was investigated. The adsorption kinetics was described by the pseudosecond-order model and the equilibrium data were well fitted with the Langmuir isotherm in case of phenol, the Sips isotherm in case of 3-aminophenol and the Redlich-Peterson isotherm in case of p-nitrophenol. The good adsorption capacity and easy separation using a magnet, recommend the magnetite/carbon nanocomposites as promising candidates for the removal of phenol and its derivatives from polluted water.
