The kinetic and thermodynamic parameters for the adsorption of ytterbium on sand samples from dilute acidic solution are presented. The sorption equilibrium constant, K c , has been calculated at different temperatures between 18 and 37°C. The sorption data fitted the Freundlich and Dubinin–Radushkevich (D–R) models well. Thermodynamic calculations showed that the sorption of ytterbium on sand was endothermic in nature
