ADSORPTION OF 4-CHLOROPHENOL USING MAGNETICNANOCOMPOSITE OF ACTIVATED CARBON /:THERMODYNAMIC AND KINETICS STUDIES

4-Chlorophenol is one of the chlorinated phenolic compounds that is highly toxic to organisms and can accumulate in their bodies biologically. These compounds can enter the environment through the wastewater industries. In this study, Activated carbon/Fe3O4 synthesized was used as a sorbent to remove 4-chlorophenol from aqueous solutions. 4-chlorophenol removal by Activated carbon/Fe3O4 was investigated using a batch system and kinetic and thermodynamic parameters of the adsorption process were calculated. Thermodynamic tests indicate that 4-chlorophenol sorption onto Activated carbon/Fe3O4 slight increase with increasing temperature, indicating the spontaneous and endothermic nature of sorption process (∆H° = 2.286 KJ.mol-1; ∆S° = 12.2 J.K-1mol-1;∆G° = -1.34 KJ.mol-1). The results indicate that the pseudo second-order model was the most suitable for describing the kinetic data.
