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.
