Abstract

Among the various adsorbents used, SAWDUST appears to be the most attractive material in terms of cost, versatility and abundance. In the present research, synthetic contaminated water with gasoline was used. ADSORPTION of PETROLEUM COMPOUNDs on four types of SAWDUST (Walnut, Poplar, Beech and Pine) was studied by using batch ADSORPTION techniques. It was found that walnut SAWDUST has higher ADSORPTION capacity than other types of SAWDUST. It was also observed that equilibrium ADSORPTION capacity was a function of pH, temperature, and H2O2 concentration in solution. Maximum ADSORPTION of PETROLEUM COMPOUNDs was obtained at pH 8. The ADSORPTION of PETROLEUM COMPOUNDs was increased by decreasing the temperature and H2O2 concentration in the solution. The maximum equilibrium capacity of walnut SAWDUST was 84.03 mgCOD/gr SAWDUST nd 606.37 mg TPH/gr SAWDUST obtained at pH 8 and+ a temperature of 10oC.The experimental ADSORPTION data were fitted to a Freundlich and Langmuier ADSORPTION model. Calculated correlation coefficients indicated that the Freundlich model was best suited, indicating that the nature of walnut SAWDUST is heterogeneous.In this study, to illustrate the relation between qe, Ce, pH and temperature, REGRESSION analysis was taken into consideration. The obtained model (with R2=0.985) improved the correlation coefficient at least 1.13% compared to the Freundlich model. The maximum and minimum error of the predicted values of qe to the experimental data was obtained as 14.29% and 0.034% for REGRESSION model, while these errors for the Freundlich model were 52.15% and 1.63%.
