NEUTRALIZATION AND CONTAINMENT OF REDOX SPECIES PRODUCED BY CIRCUMFERENTIAL ELECTRODES

摘要

There is disclosed an electrode array architecture employing continuous and discontinuous circumferential electrodes. There is further disclosed a process for the neutralization of acid generated at anode(s) by base generated at cathode(s) circumferentially located to each other so as to confine a region of pH change. The cathodes can be displayed as concentric rings (continuous) or as counter electrodes in a cross pattern (discontinuous). In this way reagents, such as acid, generated in a center electrode are countered (neutralized) by reagents, such as base, generated at the comers or at the outer ring. There is further disclosed an electrode array architecture having a plurality of electrodes in a substantially planar configuration and in a row and column format and a grid of counter electrodes also in a substantially planar configuration, wherein each electrode of the plurality of electrodes is surrounded by a grid, and wherein the plane of the plurality of electrodes is substantially parallel to the plane of the grid of counter electrodes.
