摘要
The electrochemical behavior of Nd 3+ and Ho 3+ ions on molybdenum electrode in the LiCl KCl eutectic melts has been studied by cyclic voltammetry and open circuit potentiometry. The results show that the reduction process of Nd 3+ and Ho 3+ ions on molybdenum electrode is one step three electron reversible reaction. The diffusion coefficients of Nd 3+ and Ho 3+ ions are 1 13×10 -6 cm 2·s -1 (450 ℃) and 2 142×10 -5 cm 2·s -1 (450 ℃), respectively. The measured standard electrode potential of Ho 3+ /Ho is 2 987 V(vs.Cl/Cl -), being more negative than the theoretical one, the reason of which is also discussed.
