The thermodynamics and kinetics properties and mechanism of sorption process were studied for adsorpting tyrosine in aqueous solution with multi-wall carbon nanotubes (MWCNTs), and the adsorption isotherms at different temperatures were determined. The results showed that the adsorption of the tyrosine in aqueous solution obeys well with the Freundlich isotherm, The thermodynamic parameters indicated that the adsorption reaction was a spontaneous, exothermal and decreasing entropy process,and the adsorption process had an obvious physisorption characteristic.The pseudo-second-order equation provided the best correlation for the adsorption process, being in agreement with adsorption as the rate controlling step.
