Abstract: The impedance of the electrochemical oxidation of adrenaline on a glassy carbon electrode was measured in sulfuric acid solution from 9 Hz to 15 kHz. These plots of impedance and admittance shown that the electrochemical oxidation of adrenaline is faradaie adsorption reaction. Some kinetic parameters were also determined.

Key words: Adrenaline, Electrochemical oxidation, Ac impedance, Faradaic adsorpting reaction
