Through the use of electrified microheterogeneous catalysis, which involves the application of electrifying forces to dilute dispersions of catalytically active solids, we have discovered that it is possible to destroy chlorinated aromatic and chlorofluorocarbon species in water at 0 deg C with applied dc voltages of and lt; 30 V. Chlorobenzene, Aroclor 6050 (a polychlorinated terphenyl), and CFC-113 (1,1,2-trichloro-trifluoroethane) have all been found to decompose when subjected to dispersion electrolysis in the presence of a zeolitic catalyst suspension. The reaction products are water soluble and were analyzed by gas chromatography, mass spectrometry, and ion chromatography.
