Study of some Effecting Factors on the Removal of Phenol from Aqueous Solutions by Adsorption onto Activated Carbon

The current study aims to remove organic pollutants (phenol) from industrial effluent using batch adsorption on activated carbon. Batch mode adsorption experiments were performed by varying of some different parameters such as particles size, contact time, weight of adsorbent and pH of the solution. The obtained results indicate that the adsorption of phenol increases with increasing the pH value of the solution and also mixing time. It seems that the mixing time of 120 minutes is fixed as the optimum contact time for adsorption of phenol onto activated carbon. The results also show that, the adsorption data fit well with freundlich model of adsorption isotherm.
