Abstract
By using a piezoelectric quartz crystal (PQC) with one separated elect rode as an optically-transparent electrode (OTE), a new technique of a bsorption spectroelectrochemistry (SEC) in combination with piezoelect ric quartz crystal detection is proposed. An equation connecting the a bsorbance variation due to the consumption of the colorful solution sp ecies to the frequency shift is derived. Cu(II) in glutamic acid + KNO 3 supporting electrolyte is used to test this new technique. The resul ts show that this technique can provide substantial in situ informatio n in the investigation of the electrochemical process.
