Redox Stability of Uranium(VI) in Presence of Synthetic and Natural Humic Acids


Redox Stability of Uranium(VI) in Presence of Synthetic and Natural Humic Acids

Sachs, S.; Geipel, G.; Bernhard, G.

Based on the oxidation of phenolic compounds (e.g., hydroquinone, catechol) we developed synthetic HA model substances with pronounced redox functionalities in order to study the redox behavior of HA and the redox stability of actinide humate complexes. In the present work we studied the redox stability of U(VI) humate complexes applying these synthetic HA in comparison to purified natural HA from Aldrich.

Keywords: humic acids; complex formation; uranium; redox stability; laser-induced photoacoustic spectroscopy
