Özet

This study was aimed to determine kinetic and thermodynamic behaviors of selenium on modified bentonite and activated carbon. Thermodynamic parameters such as enthalpy δH, free energy change δG and entropy change δS of selenium adsorption suggested that the adsorption of Se(IV) on activated carbon and organicinorganic modified bentonite was exothermic and endothermic process, respectively. The experimental data fitted very well the pseudo-second-order kinetic model for both adsorbents.
