Background & Objectives: Phenol is one of the hazardous pollutants in industrials effluent. This pollutant is very toxic to human and the environment. The purpose of this study was investigation of phenol adsorption capacity with egg shell waste from aqueous solution. Methods: The eggshells were dried at 70◦C and for 12 hr in oven and then shells were crushed. The surface characteristics and quantitative elemental information were studied with SEM and XRF analysis. Then the Freundlich and Longmuir adsorption isotherms and Kinetic models were applied to description of the experimental data. Results: The maximum adsorption took place in first 60min of reaction and at pH 9. With increasing the temperature the pollutant adsorption was decreased. Also absorption characteristics of this pollutant on eggshell accommodated with Freundlich isotherm (R2=0.996). Phenol removal kinetics were fitted with both pseudo-first order and pseudo-second order kinetic models. Conclusion: The presented results demonstrate clearly that eggshell is a potentially useful material to be used for the removal of phenol from aqueous solution and industrial wastewater.
