Abstract

It was shown previously that adsorption of ions at the electrical double layer of a high specific surface area carbon electrode can serve for water desalination. This is effected by assembling two such electrodes in a cell, cycling electronic charge between them and applying periodic synchronous pumping of the liquid through the cell. This process has been termed Electrochemical Parametric Pumping (ECPP). In the present article, modified charge coordinates, desalting efficiencies, isopotentiograms (analogous to adsorption isotherms) and optimization considerations of the two adsorptive electrode batch unit of the ECPP were derived and analysed on the basis of the propterties of each single electrode separately.
