Bismuth electrode is a suitable replacement for mercury electrode due to low toxicity and similar electrochemical behavior [1]. In this work for the first time a novel and stable electrode, based on Bi2O3-polymer film coated on glassy carbon was introduced. Fabrication of Bi2O3-poly p-AP (Bi2O3-Pp-AP/GCE) was carried out in two steps: first a Bi layer was formed on GCE and second, simultaneous oxidation of Bi to Bi2O3 and anodic polymerization of p-AP in weak alkaline medium were performed. The prepared electrode was characterized by CV, FT-IR (ATR), H-NMR, SEM, EDS and a suitable mechanism for electropolymerization of p-aminophenol is proposed. This electrode is stable over time and can be used repeatedly without renewing the surface of electrode.
