Abstract: The kinetic characteristics of the electrochemical oxidation of Adrenaline to adrenochrome was studied by UV-Vis Spectroscopy. The measurements showed that the electrooxidation of adrenaline to adrenochrome was typical of the first order reaction and the average apparent rate constant is 1.921×10^-4s^-1.

Key words: adrenaline, adrenochrome, electrochemical oxidation, UV-Vis absorption spectrum
