There is growing concern about wide spread contamination of surface and ground water by various organic compounds due to the rapid development of chemical, petrochemical and oil refining industries over the past several decades. So, many industrial wastes contain phenolic compounds which are difficult, or impossible to apply conventional biological treatment processes. The possibility of using Portland Cement Kiln Dust (CKD) as a low-cost and abundant adsorbent was investigated in this study for the removal of phenol from aqueous solution. Batch kinetics and isotherm studies were carried out under varying experimental conditions of contact time, phenol concentration and adsorbent dose. The suitability of some adsorption models to the equilibrium data were investigated for phenol-CKD system. Results showed that, the equilibrium data for the phenol adsorption fitted the Freundlich model best within the concentration range studied. The best percentage removal of phenol obtained in this study was at phenol concentration less than 100 ppm. The good removal efficiency of the used adsorbent may be attributed to their physico-chemical properties. The study showed that, CKD can be used as an efficient adsorbent material for removal of phenol from water and wastewater.
