Adsorption of Uranium(VI) to Manganese Oxides: Xray The mobility of hexavalent uranium in soil and groundwater is strongly governed by adsorption to mineral surfaces. As strong naturally occurring adsorbents, manganese oxides may significantly influence the fate and transport of uranium. Models for U(VI) adsorption over a broad range of chemical conditions can improve predictive capabilities for uranium transport in the subsurface.Theproduction ofelectrolytic manganese in SouthAfricamanganese dioxide (pyrolusite) asan oxidizing agent.
