摘要

研究了钒化合物稳定剂对酸性SnSO4 溶液稳定性的影响 .可见光谱分析表明稳定剂中主要含有VO2 + 和少量的V3+ ,循环伏安实验显示在 - 0 .2 0~ - 0 .55V(vs .SCE)电位范围内VO2 + 能够在阴极上还原为V3+ ,在更负的电位下V3+ 能进一步还原到V2 + .实验结果说明稳定剂中的低价钒离子有效地清除了镀液中的溶解氧 ,因而防止了Sn2 + 离子的氧化 ,显著地提高了酸性锡镀液的稳定性 .

Abstract

The effects of a vanadium compound on the stability of an acidic solution of tin(Ⅱ) sulfate were studied . The electron spectra of the solutions of stabilizer showed that the vanadium existed mainly in VO 2+ with a small amount of V 3+ in the stabilizer. The results of cyclic voltammetry revealed that VO 2+ can be further reduced to V 3+ on the cathode surface in potential range -0.2~-0.55 V(vs. SCE) and V 3+ to V 2+ at the potential more negative than -0.55 V. Both V 3+ and V 2+ can effectively eliminate the dissolved oxygen in the bath hence prevent Sn 2+ from oxidizing, which remarkably increased the stability of the tin (II) sulfate solution.
