摘要

The effects of benzaldehyde, acetophenone and 4-me-thyl 2-pentanone additives on deposition of tin in acidic solution of tin(II) sulfate were investigated. The solution containing the first two additives produced greater cathodic polarization than that of the other ketone, according to galvanostatic experiments. The kinetics of deposition of tin, with or without additives, were investigated with cyclic voltammetry and Tafel plots. Based on these results, a mechanism is proposed for the deposition process. The correlation of overpotential with the diffusion coefficient of Sn(II) in various solutions was also investigated.
