Electrochemical investigation of metal sulfides at mercury electrodes using thiourea as a source of sulfide ion

Original language description

A mercury sulfide layer was prepared at the surface of a mercury electrode by an anodic reaction in the presence of thiourea at the micromolar concentration level. Electrochemical reactions of mercury sulfide were investigated by a subsequent cathodic scan at near-neutral pH values and in the absence/presence of a second metal ion. It was proven that such prepared HgS layer is similar to that prepared by anodization in the presence of sulfide ion. Other metal sulfides were prepared via exchange reactionof mercury in HgS with a metal ion in solution, namely Zn, Ni or Cd. The method presented therein allows one electrochemical preparation and investigation of metal sulfides with no difficulty due to hydrogen sulfide volatility at pH < 12 and emphasizesthat this method can be applied to other systems consisting of a chalcogenide anion and a metal (like mercury or silver) being able of undergoing a reversible electrochemical reaction.
