چكيده فارسي :
In this study, the natural zeolite were used for the adsorption of phenol from aqueous solutions. Experiments were carried out in batch mode and under a constant temperature of 25 οC. In order to determine the best fit isotherm, the experimental equilibrium data were fitted to Langmuir, Freundlich, Temkin, and Dubnin-Radushkevich isotherms. The Freundlich isotherm model was found to be the best fitted model for describing the isotherm data. The maximum adsorption capacity was found to be 40.261 mg/g when initial concentration was 400 mg/L.
