Abstract
The electro-oxidation of hydrazine was studied in alkaline medium, bot h on pure iridium electrode and on iridium electrode modified with sub monolayer deposits of lead. The catalytic effect of these electrodes w as evaluated by cyclic voltammetry. It was demonstrated that hydrazine oxidation occurs at two potential zones and by different mechanisms. The reaction occurs at a more positive potential in the modified elect rodes surface, while I(p) (peak current intensity) remains almost cons tant.
