Description

The removal of cesium and cobalt radionuclides from aqueous chloride solutions using hydrous titanium oxide was investigated. The influence of initial ion concentration, pH, and temperature has been reported. The data obtained have been correlated with Langumir, Freundlich, and Dubinin-Radushkevich (D-R) isotherm models. The effect of temperature on the equilibrium distribution values has been investigated. The thermodynamic parameters such as free energy (ΔGo), enthalpy (ΔHo) and entropy (ΔSo) have been calculated. Maximum ion exchange capacity and the mean free energy of each studied ion have been determined using D-R isotherm model. (author)
