摘要: 通过循环伏安法和计时电位法，研究LiCl-KCl熔盐中Th4+在723～803 K内在Mo电极上的电极过程。结果表明，Th4+在Mo电极上的电极过程受离子扩散步骤控制，扩散系数D随温度T变化的经验公式为ln D＝33.94-2.879×104/T，形式电位的经验公式为E vsCl-0′/Cl2＝-3.45+7.5×10-4T。Abstract: The electrochemical process on the Mo cathode of Th4+ ion in the LiCl-KCl melts was studied by the cyclic voltammetry and chronopotentiometry. The results of research show that the electrode process is controlled by diffusion and the temperature dependence of diffusion coefficient D can be described by ln D＝33.94-2.879×104/T. The apparent potential is E vsCl-0/Cl2＝-3.45+7.5×10-4T.
