Description

Groundwater redox conditions and oxidation states of dissolved uranium were studied from natural water samples around a uranium deposit. A good consistency between dissolved U(IV)/U(VI) ratio and the measured redox potential value were observed. Dissolved redox pairs were studied in a uranium-rich groundwater sample by monitoring the Eh-change caused by acid/base addition. The results indicated that dissolved uranium in concentration of 0.8 μ mol/ l may give nernstian response at platinum electrode. (orig.) (19 refs., 5 figs., 3 tabs.)
