研究了YCl3LiClO4DMSO( 二甲基亚砜) 体系电导率与温度的关系, 及钇在Pt 和Cu 电极上的电化学行为。结果表明, Y3 + 在Pt 和Cu 电极上可一步不可逆还原为Y, 在铜电极上于- 2.500 V(vs SCE)下恒电位电解, 可获得粘附性好、Y 含量达97.9 % ( 质量分数) 的均匀沉积膜。利用循环伏安法、计时电流法、计时电位法测定了Y3 + 离子在298 K 下, YCl3LiClO4DMSO 溶液中的扩散系数为3.22 ×10 -6cm2·s-1 , 电荷传递系数为0.22 。
The relationship between conductivity and temperature of YCl3LiClO4DMSO (dimethylsulfoxide) system and the electrochemical behavior of yttrium on Pt and Cu electrodes were studied. The results show that Y3 + can be irreversibly reduced to Y on the Pt and Cu electrodes, and the potential of Y3 + is 97.9 at the potential of -2.500 V (vs SCE) % (Mass fraction) of the uniform deposited film. The diffusion coefficient of YCl3-LiClO4-DMSO solution was 3.22 × 10-6cm2 · s-1 at 298 K by cyclic voltammetry, chronoamperometry and chronopotentiometry. The charge transfer coefficient was 0.22.
