Abstract: The corncob was microwave-assistedly modified by KMnO₄ and used for adsorption of U(Ⅵ)ions from aqueous solution.The kinetics and thermodynamics of their adsorption were measured using batch experiments.The results show that the kinetics of adsorption follows well the pseudo-second order equation,indicating that the uranium adsorption by the modified corncob is mainly chemisorption. The Langmuir,Freundlich and D-R isothermal adsorption models were used to relate the equilibrium data,finding that Langmuir isotherm of monolayer adsorption is better fitting them,pointing out that the adsorption mainly occurs on surface active sites of modified corncob.The values of apparent activation energy E_a and average adsorption energy E_s support also the suggestion that adsorption of U(Ⅵ) on modified corncob is mainly chemisorption,although some physical adsorption can not be got rid of.The thermodynamic parameters(ΔH,ΔS and ΔG)calculated from the adsorption isotherms at various temperatures indicated that the adsorption of U(Ⅵ)on modified corncob is an endothermic,spontaneous process and more favorable at higher temperature.

Key words: potassium permanganate, modification, corncob, uranium, adsorption
