Abstract: This paper describes in detail the development, design, and performance of a fluorescence fiber optic spectroelectrochemical sensor for in situ determination of metal ions. The sensor design employs a bifurcated optical fiber bundle coupled to an electrochemical flow cell containing a large surface area reticulated vitreous carbon working electrode, and permits fluorescence detection of metal ions following their preconcentration by elcectrodeposition and subsequent anodic stripping and complexation with an appropriate ligand. Analytical figures of merit for fluorescence detection of aqueous copper (II) as the calcein complex are reported, and potential applications to process control and on-site environmental applications are presented.
