Description:

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.
