Electrochemically reductive dechlorination of pentachlorophenol using a high overpotential zinc cathode

Dechlorination of chlorophenols using magnesium–palladium bimetallic system

“…Electrochemical reduction/oxidation [4][5][6][7][8][9] and advanced chemical oxidation [10] of chlorophenols have been profusely studied in the last decade. Reductive electrochemical dechlorination of chlorophenols may be either complete [9] or partial resulting in accumulation of lower chlorinated phenols and phenol [5,6].…”

“…Reductive electrochemical dechlorination of chlorophenols may be either complete [9] or partial resulting in accumulation of lower chlorinated phenols and phenol [5,6]. On the other hand, both electrochemical and chemical oxidations have been reported to yield near complete mineralization of chlorophenols [7,10].…”

Dechlorination by combined electrochemical reduction and oxidation

“…These chlorinated aromatic compounds have strong resistance to physical, chemical and biological treatments and have been listed as a priority pollutant by the U.S. Environmental Protection Agency (Lin and Tseng, 1999). Wastewater containing chlorophenols has malodorous odor, high toxicity, bioaccumulation and carcinogenic potential.…”

Electrochemical treatment of pentachlorophenol in water and pulp bleaching effluent

“…Electrochemical reduction of chlorophenols which constitute a major fraction of AOX involves sequential dechlorination resulting in the accumulation of either partially dechlorinated and/or hydrocarbon end product such as phenol [25][26][27][28]. On the other hand, complete destruction of chlorophenols can be achieved by electrochemical oxidation [29].…”
