Mechanism of capture of ionic impurities from electrolytes, based on a bipolar cell of oscillating porous electrodes, spaced by the equilibrium distances

This work proposes the use of electrochemical cells (bipolar or series) like mechanism recuperate of impurities and noble species, from contaminated or impoverished electrolytes. The treated fluid circulates through porous or perforated electrodes of compound material. In order to produce successive, selective deposits of the different chemical substances, these electrodes are located spaced by specific distances. Different prototypes of electrodes were elaborated starting from a conductive base material with small dielectric zones, which can have their origin in ceramic particles or pores. The rate and selectivity of capture was related to the porosity and nature of the base of the electrode, quantified by the size, geometry, average density and distribution of the dielectric zones in the conductive matrix of the electrode. The longitudinal coordinates of each electrode are determined by means of the plainer of the electric field, which appears between the terminal electrodes, anode and cathode, polarized by an external source of tension. Using methods of finite mathematics the map of the equipotential lines was simulated and the location exact of each electrode so that by effect of his polarization it extracts a single chemical species was found. The type and the number of electrodes of the cell filter are determined by the time of residence required by the fluid to process, in order to obtain an appropriate deposit based on the volumetric flow, the composition and concentration of impurities and noble species.
