Pt Dissolution in Acidic Medium: Suitability of EQCM and ICP-MS Techniques.


Author(s): A.P. Yadav

Abstract: This study reports on the suitability of EQCM and ICP-MS techniques for studying the dissolution of Pt in acidic medium. For a 6 MHz QCM, the difference in the EQCM and ICP-MS results were pronounced when CV was carried out at 0.1Vs-1. At such high scan rate of the CV, the frequency response of EQCM does not follow the Sauerbrey equation due to heterogeneous distribution of current on the QCM surface. The active surface area of Pt and its mass loss decreases with the cycle number of CV.
