Abstract: The Fe-treated calcium phosphate (Fe-TPO4) has been prepared with FeCl3 aqueous solution. The sorption of 99MoO42- ions from aqueous solution using Fe-TPO4 as adsorbent is investigated by batch experiments. Experiments have been performed as a function of shaking time, pH, solute concentration and temperature and the experimental rate data are tested with the pseudo-second-order rate model. The adsorption data as a function of molybdate concentration obey the Freundlich isotherm. Thermodynamic parameters H0, S0 and G0 have been calculated with data of temperature studies. The positive value of H0 indicates that the adsorption of MoO42- ions on Fe-TPO4 is an endothermic process.
