    Electrochemical Studies Of N'-ferrocenylmethyl-n'-phenylbenzohydrazide At Glassy Carbon Electrode In Different Medium
    (University of Eloued جامعة الوادي, 2011-07-01) Khelef, A.; Neghmouche, N. S.; Lanez, T.
    The oxidative electrochemistry of N'-Ferrocenylmethyl-N'-Phenylbenzohydrazide FcX was studied in acetonitrile with tetrabutylammonium hexafluorophosphate as the supporting electrolyte and aqueous ethanol using the electrochemical technique. This study using cyclic (CV) and rotating disk electrode (RDE) voltammetry showed that the FcX/FcX+ redox couple is reversible in this electrolytes. The effects of changing the scan rate on the electrochemical behavior of ferrocene have been examined. A comparison of the electrochemical behavior of ferrocene and N'-Ferrocenylmethyl-N'-Phenylbenzohydrazid have been examined.

    ELECTROCHEMISTRY CHARACTERIZATION OF FERROCENE/FERRICENIUM REDOX COUPLE AT GLASSYCARBON ELECTRODE
    (University of Eloued جامعة الوادي, 2009-07-01) Neghmouche, N. S.; Khelef, A.; Lanez, T.
    In the present work the oxidation of ferrocene, , to the ferrocenium cation, , was examined in the solvents dichloromethane, and aqueous ethanol using the technique of cyclic voltammetry. The anodic (Epa) and the cathodic (Epc) peak potentials, as well as the corresponding anodic (ipa) and cathodic (ipc) peak currents, were obtained at different scan rates (0.05, 0.10, 0.30, 0.50 V.s-1). The diffusion coefficients (D) have been calculated using the Randles-Sevcik equation. The effects of changing the scan rate on the electrochemical behavior of ferrocene have been examined.
