Development of different energy sources and their related environmental issues has led to utilization of ever more chemical compounds. This in turn has caused production of various pollutants in the waste effluents of different industries. Due to environmental damaging effects of Phenol in the effluent of various chemical plants, its removal from wastewater is indeed so very important. Adsorption through granulated activated carbon (GAC) is one of the common methods to refine this pollutant from waste streams. The current research considered adsorption kinetic models in term of equilibrium isotherms for such a material. In addition, according to previous investigations, the Langmuir and Freundlich isotherms were applied to undertake the issue at hand. Pseudo first and second order models were utilized in this study. Optimally determined kinetic parameters included; KL=0.002, nf =2.38 and Kf =1.16 for the Langmuir and Freundlich isotherms. Moreover, coefficients of K1=0.01 and qe =1.44 as well as; K2 =0.0001 and qe =100 for the pseudo first and pseudo second order models; respectively indicated suitability of these equations to be used for the Phenol removal from petrochemical wastewater.
