A new modified electrode based on electrochemical oxidation of 1-amino-5,6,7,8-tetrahydronaphthalene in acetonitrile

Electrooxidative polymerization of the 1-amino-5,6,7,8-tetrahydronaphthalene (ATHN) monomer on a glassy carbon (GC) electrode was carried out in an acetonitrile solution containing LiClO4 using consecutive multisweep cyclic voltammetry and controlled potential electrolysis techniques. The factors that affected the film formation, such as monomer concentration, number of sweeping cycles, sweep rate and limits of potential cycling were investigated in detail. The obtained modified electrode was active only in acidic solutions, and its activity was found to be pH dependent. The effects of pH and temperature on the obtained modified electrode were studied. The obtained modified electrode has been found to improve the electrochemical reversibility and decrease the overpotential of hydroquinone.
