Abstract

The oxidation of sodium diethyldithiocarbamate at a glassy carbon electrode in water and water-organic mixtures in the presence of KCl and NaOH is investigated. Using cyclic square-wave voltammetry and rotated electrode voltammetry it is shown that, in water and water-ethanol mixtures, the electrode reaction is irreversible. In the case of KCl water solution, the oxidation reaction involves one electron. In the case of KCl in a water-ethanol mixture, two electrons are involved. The possible oxidation mechanism is discussed.
