Ion exchange voltammetry.

This chapter focuses on recent advances in the field of ion-exchanger based voltammetric sensors, whose widespread use has given rise to a new electroanalytical technique named ion-exchange voltammetry (IEV). The chapter starts with a brief historical overview and a short introduction to voltammetric methods of analysis, followed by the presentation of the fundamentals of ion-exchange voltammetry. Analytical advantages and limits up to the most recent developments in the technique are then presented and discussed. Typical examples of application to determinations of trace concentrations of inorganic and organic electroactive molecules of interest for environmental and biomedical analysis are finally given along with future prospects.
