Effects of Activated Carbon on Reactions of Free and Combined Chlorine With Phenols (Chlorination, Gac)
type: CreativeWork
description: The use of prechlorination in drinking water treatment results in contact of free or combined chlorine with activated carbon, which is used to remove organic compounds from water. Free chlorine reacts with a group of phenols (phenol, guaiacol, catechol, 2,6-dimethoxyphenol, p-chlorophenol) in dilute aqueous solutions (10('-5)M), to produce mono-, di-, or trichloroderivatives. When free chlorine reacts with phenols adsorbed on granular activated carbon (GAC), however, many additional products are formed. GAC promotes reactions, such as hydroxylation, oxidation to quinones, chlorine substitution, carboxylation, and dimer formation.
