摘要：

Effects of the nature of the solvent on the kinetics of the electroreduction of Cd(II) have been studied at a mercury electrode in non-aqueous solutions containing 0.1 M tetraethylammonium perchlorate as a supporting electrolyte. The standard rate constants, corrected for the double layer effects, decrease in the following order: k(s,a)(acetonitrile) > k(s,s)(propylene carbonate) > k(s,a)(formamide) > k(s,a)(dimethylformamide) > k(s,a)(dimethylsulfoxide) > k(s,a)(hexamethylphosphoramide). Two possible reaction mechanisms were considered, namely electron transfer, and cation transfer. Solvent effects were analyzed in terms of the solvation parameters of the cation and dynamical properties of the solvent.
