The model “double mixed electric layer” presents an interpretation variant for the cyclic voltammogram and for the polarography mechanism, from the point of view of the interface charge transfer phenomena, mediated by the solution donor-acceptor “impurities”. We assign a concrete physical significance for the current steps and peaks, which are characteristic to the cyclic voltammograms. The paper accredits the idea of the free electron pairs of the nitrogen, from the amino groups, which are involved in charge transfer phenomena, as a support for the electron conduction through bio-structured systems. The discussions are focused on the cyclic voltammograms associated to some electrochemical active organic compounds.
