X-ray absorption spectroscopy studies of reactions of technetium, uranium and neptunium with mackinawite.
Technetium, uranium and neptunium may all occur in the environment in more than one oxidation state (IV or VII, IV or VI and IV or V respectively). The surface of mackinawite, the first-formed ironExpand
