Speciation of U4+ in high concentrated [Cl-] solutions with a spectro-electrochemical cell


Speciation of U4+ in high concentrated [Cl-] solutions with a spectro-electrochemical cell

Hennig, C.

The coordination of the U(IV) and U(VI) ions as a function of the chloride concentration in aqueous solution has been studied by U LIII-edge extended X-ray absorption fine structure (EXAFS) spectroscopy. The oxidation state of uranium was changed in situ using a gas-tight spectro-electrochemical cell, specifically designed for the safe use with radioactive solutions. For U(IV) the complexes U(H2O)8Cl3+, U(H2O)6-7Cl2 2+ and U(H2O)5Cl+.
