Abstract:The electrodeposition of neodymium on Pt and Cu electrodes was investigated in DMSO containing NdCl3 and a small mount of water at room temperature. Cyclic voltammetryindicated that the reduction process of Nd(III) on the Pt cathode was complicated. The one-stepreduction wave showed two steps by adding 0.3mol/L ethylenediamine(EN). A delicate yellow,lustrous, strongly adhering film on the Cu electrode was obtained using potentiostatic electrolysisat -1 .80 V (vs. aq SCE).
Keywords:Electrochemical studies  Deposition  Neodymium
