Abstract
An electrochemical oxidative method destroys recalcitrant contaminants in an aqueous solution. The aqueous solution is directed to an electrochemical reactor with an anode and a cathode. A pulsating voltage is delivered across the anode and cathode generating a pulsating current to decrease energy consumption urging the recalcitrant contaminants in the aqueous solution to contact the anode and breaking strong bonds of the recalcitrant contaminants when they contact the anode.
