Abstract

Systematic experiments have shown that codeposition of Pb and Tl UPDs on silver can be obtained successfully from solution containing Pb(II) and Tl(I) in presence of suitable complexing ligands like citrate, tartrate or EDTA. The UPDs of lead and thallium resulting through codeposition are found to be mutually influenced by the concentration of the Pb(II) and Tl(I) in the media. Voltammograms have further revealed the influence of sweep rate on the coverage of Pb and Tl UPDs. Besides, voltammetric studies with programmed potential inputs indicate that the Pb and Tl UPDs are formed only on adjacent sites and the two UPDs tend to interact resulting in the formation of an alloy. Analysis of the codeposition experimental data shows the inadequacies of the existing models that have been primarily developed for single UPD systems
