Description:
Granular graphite is an ideal conductive material for electrochemical reduction technology applications in the field. Granular graphite was used to enhance the transfer of chlorinated aliphatic compounds in saturated, low permeability soils by electroosmosis. It was also used to effectively dechlorinate trichloroethylene in aqueous environments (Al-Abed and Chen, 2001). But using granular graphite alone to electrochemically dechlorinate PCBs in our preliminary experiments did not result in any dechlorination products such as biphenyl and chloride ion. However, dechlorination products were observed as a result of electrochemical dechlorination of PCBs by depositing a small amount of palladium on granular graphite electrode surfaces. Experimental results of this preliminary study on PCBs dechlorination using granular graphite will be presented.
