In this study, the adsorption kinetics, equilibrium and thermodynamics of Fe3+ ions on natural (NAP) and synthetic (HAP) apaties were examined.The adsorption efficiency of Fe3+ onto the NAP and HAP was increased with increasing temperature.The kinetics of adsorption ofFe3+ ions was discussed using three kinetic models, the pseudo-first-order, the pseudo-second-order and the intra-particle diffusion model.The experimental data fitted very well the pseudo-second-order kinetic model.
