Adsorption mechanisms and models of Sr(II),
Np(V),
Pu(IV) and
Am(III) on the loess were investigated from their adsorption and desorption properties. The distribution coefficient of
Sr and
Np was 2 - 3 orders of magnitude smaller than that of
Pu and
Am. The adsorption of
Sr and
Np was mainly controlled by the ion exchange reaction. On the other hand, the adsorption of
Pu and
Am was mostly controlled by the selective chemical reactions with Fe and Mn oxyhydroxide/oxide and humic substances. On the basis of the experimental results, several types of adsorption models of the radionuclides, considering elemental concentrations, adsorption mechanisms and kinetics, were proposed for setting up the analytical systems of radionuclide migration in the loess media.
