Abstract: The highly soluble neodymiump-toluenesulfonate in organic solvent was prepared for the first time and was used as electrolyte in DMF for the electrodeposition of neodymium. The electrode process of the reduction of Nd(Ⅲ) was studied by cyclic voltammetry, chronoamperometry and chronopotentiometry. Experimental results indicate that the electroreduction of Nd(Ⅲ) to Nd is irreversible one-step reaction, the diffusion coefficient of Nd(Ⅲ) was determined to be 4.3×10^-7cm²·s^-1at 25℃. The effect of transition metal ions such as Co(Ⅱ), Ni(Ⅱ) and Cu(Ⅱ) on the electrodeposition of neodymium was discussed. Neodymium with purplish red luster and Nd-Co, Nd-Ni films were obtained in homogeneous, dense and amorphous form by potentiostatic electrolyzing.
