Abstract:
A process for decontaminating liquid media, comprising the steps of:a) providing a plurality of sacrificial iron or mild steel electrodes contained in an electrolytic cell, said cell having an inlet and outlet for the passing contaminated liquid media through said cell,b) introducing said contaminated liquid media through said inlet to immerse said electrodes,c) maintaining said liquid media at ambient room temperature,d) applying a current across said electrodes at a voltage of 0.5 to 15 volts and a current density of about 0.002-0.05 A/cm2 through said contaminated liquid media, said current possessing alternating phase changes with a polarity reversal rate of 0.01-5 cycle/second, the amount of said current being controlled by the limitation that the concentration of the dissolved ferrous ion generated from said sacrificial iron or steel electrodes does not exceed the solubility constant at the liquid pH, Eh and temperature; ande) injecting a heated hydrogen peroxide liquid solution into said contaminated liquid media via continuous or sequential injections at a plurality of sites in the proximity of said immersed electrodes.
