Nowadays, increasing public concern have challenged the environmental problem associated with wastewater. Indeed, the removal of contaminates from wastewater is still far away from a satisfactory solution. Different processes are used for the treatment of wastewater. However, adsorption on activated carbon can be an environmentally friendly and economically sound process. In this study, olive-waste activated carbon as was employed as a novel adsorbent for efficient removal of lead (heavy metals). In the removal process the variables; pH, concentration of lead, amount of adsorbent and contact time, were studied on their influence on removal of lead, using one at a time approach, in a batch procedure on removal of lead which used 109 mg/g. Following the investigation of concentration effect, fitting the experimental equilibrium data to numerous conventional isotherm models showed that the Langmuir model with high correlation coefficient and low error analysis (R2=0.998) is more usable to explain the experimental data. The kinetic models were studied and parameters of this model was calculated. First order kinetics was predicted for adsorption with 0.99 error tolerance.
