Voltammetric study of Sn(II) reduction on a glassy-carbon electrode from sulfate-tartrate baths

The reduction of Sn(II) from sulfate-tartrate baths on a glassy-carbon electrode is studied. The influence of the tartrate anion and Sn(II) concentrations and the solution pH on the shape of the voltamograms and on the efficiency of the electrodeposition process is examined. A reaction scheme to explain the results is proposed. The voltammetric and anodic stripping analysis of the electrodeposition process shows that the optimal efficiency conditions to obtain Sn deposits are bath solutions without excess of tartrate ligand, not excessively high pH, and low overpotentials.
