Electrochemical oscillatory phenomena were first observed on mercury electrodes (including a hanging mercury drop electrode (HMDE), and liquid and solid Hg-coated gold electrodes) in the redox reaction of the O2/O2− (superoxide ion) couple in quinoline media. The current oscillation occurred during the reoxidation process of the electrogenerated O2−. It was found that the observed oscillation is really irregular, complicated and affected by many experimental factors such as electrode substrate, concentration of O2− (and O2), the rate and range of potential scan in cyclic voltammetry. A probable explanation for the observed oscillation is given.
