摘要

Disinfection byproducts (DBPs) are a group of chemical compounds formed from the reactionrnbetween natural organic matter and chemical disinfectants. The formation of DBPs in drinkingrnwater has caused serious health concerns since the discovery of trihalomethanes in chlorinatedrndrinking waters in 1970s. Many studies have evaluated factors affecting the formation of DBPsrnwithin the water treatment plants. Relatively less is known about the fates of DBPs in therndistribution system. The objective of this study was to determine the effect of temperature andrnpH on the stability of halogenated DBPs. In this study, we produce total organic halogen (TOX)rnfrom reactions between Suwannee River fulvic acid and chlorine, bromine, iodine andrnchloramine. The impact of different pH values (7.0, 8.3 and 9.5) on the degradation of TOX wasrninvestigated after oxidant residuals are exhausted. The results show that halogenated DBPsrndegrade through based-catalyzed dehalogenation processes. The relative stability of differentrnDBPs is in the order of TOCl>TOBr>TOI.
