Description

We report the first in situ and real-time observation of UV-vis absorption spectra of uranium electrodeposited on indium-tin-oxide (ITO) electrodes by slab optical waveguide (SOWG) spectroscopy. An absorption peak around 670 nm was distinguished after a 30-min holding period at -0.2 V (vs. Ag/AgCl). X-ray absorption near-edge structure spectroscopy confirmed the presence of uranium(IV) in the uranium electrodeposited on the ITO electrode. (author)
