Fig. 5.13 Time dependency of deposition Yields on fission-product rare elements by electrolytic
extraction in simulated HLLW (C.D.: 500 mA cm −2 , during 6 h electrolysis, S/V: 1/15 cm −1 ,
addition: continuously 2.53 g Pd 2+ h −1 ) (reprinted with permission from Ozawa et al. (2003)

Fig. 5.14 Cyclic voltammograms of the deposits under multiple potential scans up to the tenth
cycle. Anodic current positive. Initial potential: 1.1 V versus SSE. Initial scan direction: cathodic.
Scan rate: 0.1 V s −1 . Potential range: 0–1.3 V versus SSE. Deposit from Tc–Pd–Ru–Rh solution.
Electrolyte: 5.4 mM of Tc, 7.4 mM of Pd, 5.4 mM of RuNO 3+ and 4.7 mM of Rh 3+ in 3 M HNO 3
aqueous solution. Quantity of electricity for deposition: 378 mC. The first, the second, the fourth,
the sixth and the tenth cycles (reprinted with permission from Asakura et al. (2005) copyright 2005
