摘要：

The double-layer properties of the glassy carbon electrode in N,N-dimethylformamide (DMF) containing tetrabutylammonium perchlorate (TBAP) at different concentrations have been studied by cyclic voltammetry and impedance. The results were compared with analogous results obtained for the mercury/DMF interface. For both electrodes, the double-layer data were treated to obtain useful equations describing the dependence of the outer Helmholtz plane potential on the applied potential. The kinetics of the dissociative reduction of a sulfide in DMF/ 0.1 M TBAP was studied by convolution analysis on both glassy carbon and mercury and used as an example to test the double-layer results and compare the behavior of the two electrodes.
