Desorption of positive metal ions from the surface of a massive anode on a zeolite plate

The transfer of positive metal ions from the surface of a massive anode on a zeolite plate in an electric field that is anomalously low for this process has been considered. An explanation given to this phenomenon relies on the fact that an electric field produces a negative charge in the conductive pores of zeolite near the anode. This charge localizes on the walls of pores and generates an anomalously high local electric field on the surface of the anode. This field provides ion transfer from the anode to the zeolite surface. The presence of a threshold external field for this phenomenon has been explained.
