A Study on a Partially Immersed Gold Electrode Using an Electrochemical Quartz Crystal Impedance System

Chemical Research Institute, Hunan Normal University, Changsha 410081

Received Date: 18 February 2000

The electrochemical quartz crystal impedance system (EQCIS) has been used for the study of a partially immersed Au electrode in 0.2 mol/L NaClO₄ aqueous solution.The influences of the immersed area and height of the electrode on the EQCIS responses were evaluated, showing the highest response sensitivity to liquid loading at the center of the piezoelectric quartz crystal electrode.The increase in the immersed height of the Au electrode at oxygen reduction potentials during potential cycling was measured by this technique.
