Abstract
- Uranium (U) is a ubiquitous element in the Earth’s crust, having a concentration of about 2 ppm. Soluble hexavalent uranium (U(VI)) is reduced and immobilized in anoxic environments. The underlying reduction mechanism is unknown but is likely of critical importance to explain variability in U biogeochemical behaviors. In this study, we focused on the mechanism of reduction of U(VI) by the mixed-valence iron oxide magnetite
