Abstract
Poly-aniline (PANI) films when subjected to cyclic voltammetry in the presence of guaiacol–sulfonic acid (GSA) undergo a modification which alters their red–ox activity and extends electroactivity to neutral pH. A plausible mechanism of the modification reaction is discussed. The PANI–GSA film modified electrodes electrocatalyze the oxidation of ascorbic acid (AA) in neutral phosphate buffer (pH 7.4) with ca. 250 mV reduction of the oxidation peak potential.
