    • Abstract

       

      The electrochemical reduction of cobalt acetylacetonate (Co(acac)3) at the mercury electrode in propylene carbonate anddmso has been carried out using dc polarography, controlled potential coulometry, chronoamporometry and cyelic voltammetry. In propylene carbonate, polarograms showed two well defined waves, one wave being an adsorption pre-wave, the other an irreversible, diffusion-controlled electron transfer process. From chronoamperometry the diffusion coefficient was determined. Cyclic voltammetry confirmed the polarographic results, although additional adsorption waves were found. Indmso, results were similar to those in propylenecarbonate. However, polarograms showed no adsorption pre-wave and additional adsorption waves found in propylene carbonate in the cyclic voltammograms were absent. The mechanism of the reduction process in both solvents is discussed.
