Abstract

Abstract: Piezoelectric fiber-optic spectroelectrochemistry(PFOSEC), a new techniqueof spectroelectrochemistry (SEC)in combination with piezoelectric quartz crystal(PQC)detection is proposed.In this technique, one arm of a bifurcated fiber-opticprobe is used to conduct the incident light beam to the investigated solution andthen to the reflective electrode surface on the piezoelectric quartz crystal, and thereflection light beam is guided to the optical detector by the other arm of the opticfiber.Atypical experiinental system, Cu(Ⅱ)in glycine and KNO₃ supporting elec-trolyte, was used here to test this new technique.Results show that this techniquecan provide substantial in situ information from SEC, PQC and conventional elec-trochemistry in the investigation of the electrochemical process.This novel techiqueis recommended to find wider application in the electrochemical study not only onsolution species but also on surface phenomena.

Key words: Cornbined information, SEC, PQC, Fiber-optic, Copper, Glycine
