Abstract
The invention relates to a method for removing oxygen from a water containing reaction medium. A pair of electrodes (cathode and anode), are added to the medium, with a surfactant attached to the surface of at least one of the cathode and anode. The medium is kept at an acidic pH, and an electrical current is applied. Oxygen is drawn to the electrodes, displacing surfactant, and reacts with H+ ions and H2O molecules to form H2O2, which can then be removed.
