Ion-Transfer Voltammetry and Potentiometry of Acetylcholine with the Interface between Polymer-Nitrobenzene Gel and Water

Abstract

The transfer of acetylcholine ion at the polyvinyl chloride-nitrobenzene (PVC-NB) gel/water interface was studied by cyclic voltammetry, potential-step chronoamperometry and potentiometry. The results indicate that the PVC-NB gel/water interface or, in general, the interface between two immiscible electrolyte solutions can be used as the ion-selective electrode surface for both voltammetric and potentiometric analyses of ions, both based on the electrochemical principle of ion transfer at the interface.
