Linear Sweep Voltammetry of Ni(II), Co(II), Cd(II), and Pb(II) at Glassy Carbon Electrodes in Molten Lithium Chloride-Potassium Chloride Eutectic

The reduction of Ni(II), Co(II), Cd(II), and Pb(II) was studied at glassy carbon electrodes in molten lithium chloride‐potassium chloride eutectic at 450°C using the technique of linear sweep voltammetry. Peak‐shaped voltammograms were obtained at scan rates of . Linear dependence of peak currents on metal ion concentration and the square root of voltage scan rate was obtained for all the cations studied. The diffusion coefficients of Ni(II), Co(II), Cd(II), and Pb(II) were calculated from the experimental data and found to be 1.26, 1.02, 0.98, and , respectively.
