Özet

The electrooxidation of. physostigmine (PHY) has been investigated at different pH values at platinum, ruthenium, carbon paste and glassy carbon electrodes. It has been found that Ru and Pt electrodes played an important role in the oxidation. The nature of the curves are strongly dependent upon the scan rate, supporting electrolyte and the pH values of the solutions. With glassy carbon electrode, the results are highly dependent upon the activation process of the electrode. Activated glassy carbon and oxidized Pt and Ru electrodes give the best results. Suitable mechanisms for oxidation of PHY in both acidic and basic media have been proposed.
