Abstract

Electrochemical measurements of LaCl₃ were obtained in eutectic LiCl-KCl at 773 K. Cyclic voltammetry data were acquired using a tungsten electrode LaCl₃ amounts in the molten salt in the range of 0.5 to 3.0 wt%. Both cyclic voltammetry and Tafel analyses of the data resulted in calculation of values for the charge transfer coefficient (0.262), diffusion coefficient (1.67 × 10^-5 cm² s^-1), exchange current density (0.0148 to 0.0473 A cm^-2), and charge transfer resistance (0.404 to 1.99 Ω) related to lanthanum ions in the molten salt. Calculated values were compared to those available in the literature. The values of parameters found in literature varied significantly in comparison to those in the present study due to dissimilar experimental conditions, e.g., electrode material, temperature, and LaCl₃ concentration.

Investigation on Reaction Probabilities for Cyclic Voltammetry of Zirconium in LiCl-KCl Eutectic Molten Salt via Reverse-Engineering Method

Journal Article Rakhshan Pouri, Samaneh ; Phongikaroon, Supathorn - Transactions of the American Nuclear Society

This work focuses on a reverse-engineering program design for the cyclic voltammetry (CV) method to help illustrating, enhancing, and providing robustness in detection probability of the reactions during an electrorefining process. Analyzing the reactions from CV plots for 1.07, 2.49, and 4.98 wt% of zirconium chloride (ZrCl{sub 4}) in a LiCl-KCl molten salt at 773 K under different scan rates from Hoover's study has been accomplished. The results provide the current (Amp) versus potential (V) to investigate the optimum probability of the reactions at each peak. All simulations have been done through the commercial software MATLAB by using various experimentalmore »« less
Electrochemical measurement and analysis of YCl₃, ScCl₃, GdCl₃ and MgCl₂ in molten eutectic LiCl-KCl

Journal Article Shaltry, Michael R. ; Tripathy, Prabhat K. ; Yoo, Tae-Sic ; ... - Journal of Electroanalytical Chemistry

Here, electrochemical measurements of YCl₃, ScCl₃, GdCl₃ and MgCl₂ were obtained in the molten eutectic LiCl-KCl at 773 K using a three-electrode configuration. Tungsten rods were used as the working and counter electrodes. Three reference electrodes of differing composition (glassy carbon, nickel wire, and Ni/NiO) were utilized to acquire electrochemical measurements of the analyte salts. Cyclic voltammetry data were analyzed to determine diffusion coefficient and exchange current density values. The measured cyclic voltammograms were normalized with respect to both lithium reduction and chloride ion oxidation potentials. Such a normalization technique is effective for comparing experimentally obtained cyclic voltammetry data tomore »« less

Electrochemical studies of LaCl{sub 3} and GdCl{sub 3} dissolved in fused LiCl-KCl

Journal Article Lantelme, F ; Berghoute, Y - Journal of the Electrochemical Society

Molten systems are important as reaction media for the winning of strong oxidation or reducing elements such as fluorine, alkaline, and alkaline earth metals and aluminum. Recently, fused salt electrochemistry has been used for the preparation of refractory metals opening the way to the deposition of metals in solid state. The thermodynamic properties of solutions of lanthanum or gadolinium chlorides in mixed molten LiCl-KCl were determined by electromagnetic force (emf) measurements of LaCl{sub 3} or GdCl{sub 3} formation cells. The temperature dependence of the emf between 380 and 590 C was used to calculate the Gibbs energy and the enthalpymore »« less

Electrochemical Impedance Spectroscopy and Cyclic Voltammetry Methods for Monitoring SmCl₃ Concentration in Molten Eutectic LiCl-KCl

Journal Article Shaltry, Michael R. ; Allahar, Kerry N. ; Butt, Darryl P. ; ... - Journal of Nuclear Fuel Cycle and Waste Technology

Molten salt solutions consisting of eutectic LiCl-KCl and concentrations of samarium chloride (0.5 to 3.0 wt%) at 500 C were analyzed using both cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS). The CV technique gave the average diffusion coefficient for Sm³⁺ over the concentration range. Equipped with Sm³⁺diffusion coefficient, the Randles-Sevcik equation predicted Sm³⁺ concentration values that agree with the given experimental values. From CV measurements; the anodic, cathodic, and half-peak potentials were identified and subsequently used as a parameter to acquire EIS spectra. A six-element Voigt model was used to model the EIS data in terms of resistance-timemore »« less

In Situ Electrochemical Study of the Coexistence of Eu ³⁺ and Eu ²⁺ in Molten LiCl-KCl by Rotating Disc Electrode

Journal Article Ge, Jianbang ; Park, Jaewoo ; Leong, Amanda ; ... - Journal of the Electrochemical Society

In this study, a graphite rotating disc electrode was successfully designed and applied to conduct electrochemical measurements under flow conditions in molten LiCl-KCl at 773 K. The concentration and diffusion coefficients of Eu³⁺and Eu²⁺in molten salt were quantitatively measured with this electrode by applying in situ cyclic voltammetry and chronoamperometry techniques. The initial concentration ratio of Eu³⁺/Eu²⁺in LiCl-KCl-0.5 wt% EuCl₃was calculated to be 2.37. The calculated diffusion coefficients of Eu³⁺and Eu²⁺in the salt were 9.31 ± 0.06 × 10^-5cm²s^-1and 9.65 ± 0.6 × 10^-5cm²s^-1, respectively. A decrease of the diffusion coefficient of Eu³⁺and Eu²⁺was observed at a higher concentration ofmore »« less
