Abstract:
The electrochemical behavior of L-cysteine, 3-mercaptopropionic acid, dimercaptopropanesulfonic acid and dimercaptosuccinic acid, was examined at a mercury film electrode, gold electrode and platinum electrode. The effect of scan rate, pH and concentration were determined by cyclic voltammetry. The comparison of the cyclic voltammograms, established a great similarity among the monomercapto compounds at different molecular weight and structure and among the dimercapto compounds that were studied. Differences between the behavior of dimercapto and monomercapto compounds were also established. The cyclic voltammetry of arsenic is affected by the presence of cysteine, and the formation of an arsenic-cysteine complex is established by the shift of the oxidation potential of elemental arsenic at a gold electrode.
