Voltammetric Determination of Vanillin Using a Pretreated Pencil Graphite Electrode

Abstract: In this study, a sensitive voltammetric method for the determination of vanillin in commercial food products was proposed using a pencil lead as an electrode material. In the cyclic voltammograms of vanillin recorded in pH 8.0 Britton Robinson buffer at the pre-oxidized pencil graphite electrode (p-PGE), a sharp peak was observed at about 520 mV (vs. Ag / AgCl electrode) attributed to the oxidation of vanillin. Subsequently, the voltammetric determination of vanillin based on its oxidation at p-PGE was carried… Show more

“…Many works have been reported regarding the study of the electrochemical behaviour of Gan [18][19][20][21][22][23][24][25], Acy [26][27][28][29][30][31][32][33][34][35][36][37] and TG [38][39][40][41][42][43][44][45][46][47][48] upon a variety of unmodified and modified electrodes. These electrodes exhibited good responses in determining for pharmaceutical derivatives of guanine using differential pulse voltammetry, square wave stripping voltammetry, amperometry, potential scanning voltammetry and square wave voltammetry electrochemical techniques.…”
