✦ Synopsis


By using a piezoelectric quartz crystal (PQC) with one separated electrode as an opticallytransparent electrode (OTE), a new technique of absorption spectroelectrochemistry (SEC) in combination with piezoelectric quarts crystal detection is proposed. An equation connecting the absorbance variation due to the consumption of the colorful solution species to the frequency shift is derived. Cu(II) in glutantic acid + KNO, supporting electrolyte is used to test this new technique. The results show that this technique can provide substantial in situ information in the investigation of the electrochemical process.
