Effects of activated carbon on the reactions of combined chlorine with phenols

Disinfection byproduct formation during drinking water treatment and distribution: A review of unintended effects of engineering agents and materials

“…When chlorine, chloramines or chlorine dioxide is used for pre-oxidation, their reactions with AC and adsorbed compounds onto AC inevitably occur (Table 2). The pre-treatment has been demonstrated to produce toxic by-products and/or increase total organic halogen (TOX) concentrations, as shown in Table 2 (McCreary and Snoeyink, 1981;Chen et al, 1982;Voudrias et al, 1985b;Stüber et al, 2005). Several chlorinated organic compounds and chlorate were found to be generated from the reactions of chlorine-containing disinfectant (i.e.…”

“…Formule (VOUDRIAS et al, 1985b) ; (") Structures proposées par les banques de données, E : structure confirmée par l'injection d'un étalon (comparaison du temps de rétention et du spectre de masse) ; +++ : structure confirmée par comparaison avec les données bibliographiques ; ++ : structure très probable d'après les données de la littérature ; + : structure très probable…”

γ-Radiolysis of aqueous 2-chloroanisole

“…Chlorinated and other substituted benzenes, phenols and other aliphatic carbons represent the most important environmental pollutants Speece, 1990, 1991a, b), thus contaminating waste water and ground water. Even under drinking water treatment procedure their formation may occur because granulated activated carbon (GAC) oxidized by chlorine becomes very active towards phenol (Voudrias et al, 1984(Voudrias et al, , 1985a.…”
