ABSTRACT:
A method for detecting and destroying various chlorinated hydrocarbons and unsaturated hydrocarbons in the environment using electrochemical techniques has been invented. By concentrating the chlorinated hydrocarbons or unsaturated hydrocarbons in a solvent by liquid-solid or liquid-liquid extraction, and then passing current through the solvent extractant containing the chlorinated hydrocarbons or unsaturated hydrocarbons electrochemically removes chlorine and oxidizes unsaturated hydrocarbons. The potential is measured to correlate to the concentration of the chlorinated hydrocarbon specie.
