Uranium hydroxide/oxide deposits on uranyl reduction

Ouchi, Kazuki; Matsumura, Daiju; Tsuji, Takuya; Kobayashi, Toru; Otobe, Haruyoshi; Kitatsuji, Yoshihiro

RSC Advances (Internet), 13(24), p.16321 - 16326, 2023/05

 Times Cited Count:0 Percentile:0(Chemistry, Multidisciplinary)

We clarified the chemical state transformation of deposits following the reduction of uranyl ion (U$$^{rm VI}$$O$$_{2}$$$$^{2+}$$) from the results of electrochemical quartz crystal microbalance, impedance spectra and X-ray absorption fine structure measurements. We propose the following deposition mechanism: (1) U$$^{rm IV}$$ is formed by the disproportionation of U$$^{rm V}$$. (2) U$$^{rm IV}$$ forms U$$^{rm IV}$$ hydroxide deposits, and (3) finally, the hydroxide deposits transform into U$$^{rm IV}$$ oxide, generally having a larger electrical resistance than the former.
