Abstract
ABSTRACTBy using electrochemical techniques in simultaneous combination with EXAFS, we can stabilize a targeted charge state of a solution complex and probe the coordination of selected actinide (An) ions. In addition, we can acquire sufficient XANES over a range of controlled electrochemical potentials, in the vicinity of a redox couple, to perform a Nernst analysis. The prospect of this technique to provide here-to-fore unattainable information is demonstrated through examples of Np, Pu, and Bk speciation in solution.
