The paper presents a study of the voltammetric behaviour of Enoxil on a platinum electrode in aqueous solution of 0.1M NaClO₄. On the basis of plotted cyclic voltammograms (CV) was found that the Enoxil undergoes a quasi-reversible redox process, which may be used for identification and dosage of this biologically active compound. The values of the standard reduction and oxidation potentials and the formal redox potential of Enoxil were determined and by the rotating disk electrode technique (RDE) was followed the determining mechanism of redox process undergone by Enoxil in the considered environment. Another aim of this research was to study the influence of different aditions of ascorbic acid and oxalic acid, which facilitates the conjugated redox process, specific to the Enoxil, and the addition of hydrogen peroxide, which leads to the consumption of the Enoxil, the oxidizing action of the hydrogen peroxide is further manifested on this product that was obtained by grinding the grape seeds, extraction with ethanol and treatment with hydrogen peroxide.
