Electroreduction of Cu (II) and Se (IV) ions on Vitreous Carbon Electrode
The electroreduction of copper (II) and selenium (IV) ions on vitreous carbon electrode from sulfate electrolyte has been studied. The studies have shown that during the concurrent reduction copper is first reduced within 0.15-0.05 V range of potentials. In this range of potentials the cementation r...

| Summary: | The electroreduction of copper (II) and selenium (IV) ions on vitreous carbon electrode from sulfate electrolyte has been studied. The studies have shown that during the concurrent reduction copper is first reduced within 0.15-0.05 V range of potentials. In this range of potentials the cementation reaction to form selenium compounds with copper is possible. Qualitative characteristics of Cu2Se compound have been obtained at −0.3 V potential. The composition has been confirmed by XPA and electron-probe analysis. |
