Electrode reaction of the Np³⁺/Np couple at liquid Cd and Bi electrodes in LiCl–KCl eutectic melts

Electrochemical behavior of actinides and actinide nitrides in LiCl–KCl eutectic melts

“…By considering reported values of G 0 AnBi n and c Bi,Metal , the estimated E values are also in good agreement with the experimental values [15,16,25]. This result suggests that the potential shift almost corresponds to the free energy of formation of the intermetallic compound, AnBi n (Fig.…”

“…Therefore, potentiometric methods were applied in order to obtain accurate values of the redox potentials of the An 3+ /An and Ln 3+ /Ln couples. The formal potentials of the An 3+ /An and Ln 3+ /Ln couples, E 0 An 3+ /An or E 0 Ln 3+ /Ln , in the LiCl-KCl melts obtained by the measurement of electromotive force are shown in Table 1 [15,16]. The E 0 An 3+ /An and E 0 Ln 3+ /Ln values were obtained by extrapolation of the linear E versus ln c AnCl 3 or ln c LnCl plot to the intercept.…”

Evaluation of the thermochemical properties of Ho–Cd intermetallic compounds using electrochemical techniques

“…5 In this way, the electrochemical behaviour of some Ans and Lns has been examined using a liquid cadmium cathode. [5][6][7][8][9][10][11][12][13][14][15][16][17][18][19] Nevertheless, there are still many of them that need to be explored in terms of electrochemical and thermodynamic properties. This is the case of holmium, a heavy lanthanide object of the present paper, in which its electrode reactions at a Cd coated W electrode, were investigated, with the aim to calculate the Gibbs free energies of formation of the different Ho-Cd intermetallic compounds, as well as the activities and relative partial molar Gibbs energies of Ho and Cd, by means of electrochemical techniques.…”

Thermodynamic properties of thulium and ytterbium in fused NaCl–KCl–CsCl eutectic

“…Also the study of Tm is interesting as it has exactly the same electrochemical behavior as Am. In addition, REE have similar chemical properties [6][7][8][9][10][11][12][13][14][15][16][17][18][19]37] to those of actinides [20][21][22][23][24][25][26][27][28][29][30] hence separation between these groups of elements is very difficult. For this reason, a good knowledge of the base thermodynamic properties of REE and An in the proposed separation media is very important.…”
