Abstract EN
Distribution coefficient of cesium on soil (yellow sand and clay) with and without alumina as a colloidal material was measured by batch technique.
The adsorption of Cs+ ions from aqueous sodium chloride solution onto yellow sand and clay in absences and presence of Al2O3, was investigated under different physicochemical conditions including contact time between liquid and solid phases, pH, ionic strength, initial metal ion concentration and temperature.
Pseudo firstorder and pseudo second-order kinetic models were used to analyze the sorption rate data and the results showed that the pseudo second-order model is best correlation the kinetics data in all studied sorption processes.
Both Freundlich and Langmuir isotherm models were applicable to describe the adsorption of Cs+ ions by yellow sand with and without alumina but in case of clay with and without alumina Langmuir model not applicable.
The maximum sorption capacities of clay in absences and presence of Al2O3 were found to be greater than that of yellow sand with and without Al2O3.
The maximum sorption capacities for two sorbents were increased in presence of colloid alumina thane in absences.
The sorption capacity is reduced at high temperature was related to the partial enhancement of desorption from yellow sand and clay surfaces.
The adsorption of Cs+ ions by yellow sand and clay with and without alumina was exothermic reaction.
