WebJul 16, 2008 · TCE dechlorination presented in the literature utilized electrodes made with material that may not be practical for field use. Granular graphite was used as electrode material to effectively dechlorinate TCE in aqueous environments. Granular graphite is a highly conductive material with a large surface area for reactions. WebParticle efficiency, defined as the fraction of the Fe0in the particles that is used to dechlorinate TCE, was determined under iron-limited conditions. Both particles had a core/shell structure and similar specific surface areas (∼30 m2/g). Using excess iron, Fe/B transformed TCE into ethane (80%) and C3−C6 coupling products (20%).
