Electrochemical measurements of the effects of inertial acoustic cavitation by means of a novel dual microelectrode

A novel dual microelectrode system has been developed to study the effects of cavitation at the solid/liquid interface. By sealing lead and platinum microelectrodes in close proximity, the mass transfer and surface effects from the same inertial cavitation event have been recorded simultaneously for the first time. A number of advantages of the system have been outlined. In addition supporting evidence for an erosion/corrosion mechanism on the lead electrode is reported. (C) 2004 Elsevier B.V.
