Oscilloscopic Polarography at Glassy Carbon Electrodes in Molten Lithium Chloride-Potassium Chloride Eutectic.

Abstract

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 450C using the technique of oscilloscopic polarography. Peak shaped voltammograms were obtained at scan rates of 10 millivolts to 1 volt/second. Linear dependence of peak current 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 1.29 x 10 to the -5th sq cm/sec, respectively.
