Electropolymerization of 4-amino-3-hydrazino-5-mercapto-1,2,4-triazole (Purpald？)

In this study electropolymerization of 4-amino-3-hydrazino-5-mercapto-1,2,4-triazole (Purpald？) on the disposable pencil graphite electrode (PGE) was described and the electroactivity of the polymer film coated and naked PG electrodes were checked against K3[Fe(CN)6] / K4[Fe(CN)6] in pH 8 Britton？Robinson (BR) buffer solution. The electropolymerization of Purpald？ film was performed with cyclic voltammetry (CV). The optimal conditions of Purpald？ film coated electrode were performed using electrochemical impedance spectroscopy (EIS). The conductivity of the Purplad？ modified electrodes was compared with bare and p-phenylenediamine modified PG electrodes by EIS technique. The results indicated that electrosynthesized poly(Purplad？) film could be used for modification of electrodes to be used in electrochemical analysis and sensor applications
