Adsorption processes are being widely used by various researchers for the removal of heavy metals from waste water and activated carbon has been frequently used as an adsorbent. Despite its extensive use in water and wastewater treatment industries, activated carbon remains an expensive material. In recent years, the need for safe and economical methods for the elimination of heavy metals from contaminated water has necessitated research interest toward the production of low cost alternatives to commercially-available activated carbon. Activated carbon taken from pine cone (ACPC) was used as adsorbent to remove Fe+2 ions from industrial wastewater. In this study, ozonation, ozon pumping to the porous media, was the effective reason of removal efficiency increasing. Ozonation has been conducted on the adsorption process of removing Zn+2 under specific conditions, which is the same conditions and pollutant that were studied in the aforementioned research, where the removal efficiency before and after ozonation was compared and found it reached to 99.55% instead of what was it been by 96%. Batch adsorption experiment was conducted to examine the effects of adsorbent dosage, contact time, pH and stirring rate on adsorption of Fe+2 from the wastewater. The obtained results showed that, the adsorption of the metal ions was adsorbent dosage, contact time, pH and stirring rate dependent. The optimum adsorbent dosage, stirring rate and pH, were found to be at 3 g, 250 rpm, 60 ppm initial concentration of Fe+2 and pH 6 respectively. Environmental parameters were studied in this work including pH, total dissolved solid and total suspended solid. Kinetic studies were evaluated by Langmuir, Freundlich and Elvich isotherm models. Frendlich isotherm afforded the best fit to the equilibrium data. Maximum adsorption of Fe (II) was 97% observed in specific condition.
