Archivio Istituzionale della RicercaWe present a generalization of the Poisson−Nernst−Planck model for a dielectric liquid containing two groups of ions limited by Ohmic electrodes. The theoretical results are used to interpret experimental results of impedance spectroscopy of pure water limited by electrodes of different metallic materials. The agreement between theoretical predictions of the presented model and experimental data obtained with pure water is rather good for all types of electrodes.

Abstract
We present a generalization of the Poisson−Nernst−Planck model for a dielectric liquid containing two groups of ions limited by Ohmic electrodes. The theoretical results are used to interpret experimental results of impedance spectroscopy of pure water limited by electrodes of different metallic materials. The agreement between theoretical predictions of the presented model and experimental data obtained with pure water is rather good for all types of electrodes.
