Author(s): N. S. Neghmouche, T. Lanez*
Abstract: The study was conducted on a fixed electrode of glassy carbon with different scanning speeds (0.05, 0.10, 0.30, 0.50 Vs-1) and we had a study on rotating electrode with different rotation speeds (400.600.800.1000 rpm), and we calculate some electrochemical parameters starting from the polarization curves of ferrocene, The parameters are : The anodic (Epa) and the cathodic (Epc) peak potentials, as well as the corresponding anodic (ipa) and cathodic (ipc) peak currents, and the half-wave potentials (E1/2) were obtained at different scan rates and different rotation speeds. The diffusion coefficients (D) have been calculated using the Randles-Sevcik equation.
