Adsorption phenomenon and external field effect on an isotropic liquid containing impurities - art. no. 021101

The steady-state distribution of ionic charges in a liquid, in the presence of surface adsorption, is determined. The effect of an electric field appl ied by means of blocking electrodes is considered. The analysis shows that the surface adsorption of ions dissolved in the liquid is responsible for a n asymmetry in the electric-field distribution. In the model, the liquid is assumed to be dielectric but to contain impurities. These impurities, by m eans of a chemical reaction, can bring about ions. The theory takes into ac count the activation energy for the ionization chemical reaction and the ad sorption energy of the ions at the surface.
