Absract
The thermal mechanism of the effect of high-frequency electromagnetic fields on adsorption processes is well studied, and it is known that volumetric heating of the medium reduces adsorption. It is of interest to study other, non-thermal mechanisms of influence of high-frequency electromagnetic fields on adsorption processes. In the article the non-thermal effect of high-frequency electromagnetic fields on adsorption of polar components of oil on non-polar adsorbent (surface of pore channels) was evaluated. The non-thermal effect of the field is due to the effects of polarization of polar molecules on the surface of the nonpolar adsorbent, taking into account the orientational and deformation polarization of molecules. To evaluate the effect, we consider the limiting case when the adsorbent surface is modeled as a conducting metallic surface and the system is subjected to an external electrostatic field. Generalizing the obtained evaluation results to the case of high-frequency electromagnetic fields, it is found that the field enhances the adsorption of polar molecules on the adsorbent surface for non-thermal effects.
Materials and methods
The article used models and methods of electrostatics that describe the interactions of polar molecules with a condution surface, and also used methods of statistical physics to describe adsorption processes.
