ELECTROCHEMICAL DECHLORINATION OF TRICHLOROETHYLENE USING GRANULAR-GRAPHITE ELECTRODES
Chen**, J. L., S R. AlAbed*, J A. Ryan*, AND Z. Li**. ELECTROCHEMICAL DECHLORINATION OF TRICHLOROETHYLENE USING GRANULAR-GRAPHITE ELECTRODES. 220th ACS National Meeting, Emerging Technologies in Hazardous Waste Management, Washington, DC, 8/20-24/00.
Electrochemical dechlorination of TCE was conducted in a glass column using granular graphite as electrodes. A constant voltage of 15 volt was applied resulting in 60-62 mA of current. Approximately 4-6% of the TCE was dechlorinated. Among the reduced TCE, more than 95% was completely dechlorinated to methane, ethane, ethene, and acetylene. Vinyl chloride and all three dichloroethylene isomer were detected. The results shows the feasibility of using granular graphite-filled hydraulic fractures (cathode) as in-situ treatment zones for chlorinated organic compounds during electroosmosis.
