Electrochemical Behavior of Ph Using EQCM Technique in Alkaline Aq ueons Solution

Abstract

Electrochemical behavior of lead was investigated using EQCM technique at Au electrode in alkaline aqueous solutions. The interfacial mass at Au electrode modified with Pb monolayer remarkably decreases by the oxidation and dissolution of Pb in the range 0.25 to 0.6 V. A Pb thin film deposited on the electrode is easily oxidized and dissolved in the range 0.25 to 1.0 V.
