The electrochemical behavior of arylidene adipic acid dihydrazide derivatives (I-VII) was investigated in Britton- Robinson buffer solutions containing 50% (v/v) ethanol using three different electrochemical techniques namely: DC-polarography, cyclic voltammetry and chronocoulometry. DC-polarograms displayed only one irreversible diffusion-controlled reduction waves overall the pH range studied from 2.0 to 11.0 except VII, which showed two irreversible reduction waves. The diffusion current of the reduction waves in acidic solutions is almost twice that in alkaline ones. Cyclic voltammograms showed one or two irreversible reduction peaks depending on the pH of the electrolysis solution and the nature of substituent. Chronocoulometry indicated that the compounds under study are not adsorbed on the electrode surface. The kinetic parameters of the electrode reaction and the effect of substituent on the half-wave potential were determined and discussed. Also, the electrode reaction mechanism was proposed and discussed.
