Description:
This study investigates electrochemical degradation of Trichloroethylene (TCE) using granular graphite as electrodes in a flow-through reactor system. The experiments were conducted to obtain information on the effect of voltage and flow rates on the degradation rates of TCE. The degradation rate of TCE increased with applied voltage. The calculated rate constants at 5, 10, and 20 volts were 0.01, 0.04, and 0.06 h(-1), respectively. Chloromethane (CM) was the major chlorinated daughter products. The ratio of TCE converted to CM increased as the applied headspace pressure increased as a result of methane, ethane, and ethylene production. The origin of gases was undetermined as the solution matrix was also reduced to methane, ethane, and ethylene. This study provides preliminary data for designing an electrochemical system capable of treating soil and water contaminated with chlorinated organic compounds.
