| description | The properties of soil at disposal sites are very important for geological
disposal of very low level radioactive waste in terms of U(VI). In this
study, soil from a candidate very low level radioactive waste disposal site
in China was evaluated for its capacity on uranium sorption. Specifically,
the equilibrium time, initial concentration, soil particle, pH, temperature,
and carbonate were evaluated. The results indicated that after 15-20 days of
sorption, the Kd value fluctuated and stabilized at 355-360 mL/g. The
adsorptive capacity of uranium was increased as the initial uranium
concentration increased, while it decreased as the soil particle size
increased. The pH value played an important role in the U(VI) sorption onto
soil, especially under alkaline conditions, and had a great effect on the
sorption capacity of soil for uranium. Moreover, the presence of carbonate
decreased the sorption of U(VI) onto soil because of the role of the strong
complexation of carbonate with U(VI) in the groundwater. Overall, this study
assessed the behavior of U(VI) sorption onto natural soil, which would be an
important factor in the geological barrier of the repository, has
contribution on mastering the characteristic of the adsorption of uranium in
the particular soil media for the process of very low level radioactive waste
disposal. |
