Electrochemical behaviour of curium(III) ions in fused 3LiCl–2KCl eutectic

Evaluation of Apparent Standard Potentials of Curium in LiCl-KCl Eutectic Melt

“…4, our data are in good agreement with Osipenko's data 13 and are lower than Martinot's data. 29 The dependency of the apparent standard potential on temperature was almost same in the case of Np, Pu, Am, and Cm, as shown in Figs.…”

“…6 together with reported data. 12,13 A linear dependence of apparent standard potentials on temperature yields to the following equation:…”

“…Among MAs, reliable apparent standard potential data of Np [2][3][4][5][6][7] and Am [8][9][10][11] in LiCl-KCl eutectic melt were reported. As for Cm, a set of data on the apparent standard potentials of Cm had been reported by Martinot 12 before new data were reported by Osipenko 13 in 2011. And there is significant difference between two data.…”

“…In previous studies, Cm 3+ ions were introduced into LiCl-KCl as CmH 3 12 or as curium chloride prepared by the reaction of Cm 2 O 3 with chlorine gas in the melt. 13 In the present study, Cm 3+ ions were introduced into LiCl-KCl eutectic melt as CmCl 3 which was synthesized by the solid-state reaction of CmN with CdCl 2 . A small electrochemical cell was designed for the electrochemical measurement using a small amount of the highly radioactive MAs (the amount of which is limited lower than 30 mg, because the maximum handling amount of Cm-244 in our hot cell is 30 mg) contained in molten salts.…”

Electrochemistry of Tm(III) and Yb(III) in Molten Salts

“…Special attention is devoted to rare earth elements (REE) mainly due to its neutronic poison effect and the high content into the spend fuel. In addition, REE have similar chemical properties [Bermejo et al, 2006[Bermejo et al, , 2007[Bermejo et al, , 2008a[Bermejo et al, , 2008bCastrillejo et al, 2005aCastrillejo et al, , 2005bCastrillejo et al, , 2005cCastrillejo et al, , 2009De Cordoba et al, 2004Kuznetsov et al, 2006;Smolenski et al, 2008aSmolenski et al, , 2008b] to those of actinides [Fusselman et al, 1999;Morss, 2008;Osipenko et al, 2010Osipenko et al, , 2011Roy et al, 1996;Sakamura et al, 1998;Serp et al, 2004Serp et al, , 2005aSerp et al, , 2005bSerp et al, , 2006Serrano & Taxil, 1999;Shirai et al, 2000] hence separation between these groups of elements is very difficult. For this reason, a good knowledge of the basic properties of REE in the proposed separation media is very important.…”
