Kinetic model of electrochemical aqueous coolant decontamination

In an electrochemical cell comprising an equilibrium metal felt anode based on a sorption filter, as well as a highly polarized cathode having a significantly smaller surface area, hydroxonium cations and hydroxide anions form a double electric layer in a viscous sublayer of the aqueous coolant near the cathode surface. If the cathode electric potential allows for an electron exchange between these ions, then the double layer becomes a powerful source of hydroxyl radicals, which are chemically active outside the cathode. Then, when the aqueous coolant flows through this cell, trace radionuclide impurities will be extracted from it by the adsorption on a renewable surface of a metal felt, continuously oxidized by hydroxyl radicals.
