Anaerobic dechlorination of 2,4-dichlorophenol in freshwater sediments in the presence of sulfate

Abstract

In the presence of added sulfate, 2,4-dichlorophenol and 4-chlorophenol were transformed stoichiometrically to 4-chlorophenol and phenol, in anaerobic freshwater lake sediments between 18 and 40°C. The concomitantly occurring sulfate reduction reduced the initial sulfate concentration from 25 mM to about 6 to 8 mM and depressed methane formation.
