Abstract
The study has shown that in a soil with a logKd of 4–5 for uranium between the aqueous and the solid phase only some 20 % of the soil inventory of uranium is mobilized. Five consecutive L/S 10 extractions with alkali released some 75 % of the uranium inventory but not the entire content of organic matter. The mobilization of uranium coincides with that of organic matter as evidenced by size exclusion chromatography and ICP-MS. The stationary uranium coelutes with to a high extent with humic and fulvic substances.
