Effects of metal ions on disinfection byproduct formation during chlorination of natural organic matter and surrogates.
The effects of calcium, cupric, ferrous and ferric ions on the formation of trihalomethanes (THMs) and haloacetic acids (HAAs) were investigated using natural organic matter (NOM), small molecular weight NOM surrogates and natural water samples. The results showed that the effects were greatly dependent on the disinfection byproduct (DBP) precursor structure and molecular weight, and metal ions...
متن کاملModeling volatilization and adsorption of disinfection byproducts in natural watersheds.
It is an emerging concern that a series of disinfection byproducts (DBPs) produced in wastewater effluent have adversely impacted the downstream aquatic system and drinking water resources. The occurrence, fate, and transport of DBPs on receiving waterbodies, however, are currently not well-documented. To fill the knowledge gap, this study simulated the effects of volatilization and adsorption ...

متن کاملCharacterization and determination of chloro- and bromo-benzoquinones as new chlorination disinfection byproducts in drinking water.
We report the characterization and determination of 2,6-dichloro-1,4-benzoquinone and three new disinfection byproducts (DBPs): 2,6-dichloro-3-methyl-1,4-benzoquinone, 2,3,6-trichloro-1,4-benzoquinone, and 2,6-dibromo-1,4-benzoquinone. These haloquinones are suspected bladder carcinogens and are likely produced during drinking water disinfection treatment. However, detection of these haloquinon...
متن کاملChlorination of oxybenzone: Kinetics, transformation, disinfection byproducts formation, and genotoxicity changes.
UV filters are a kind of emerging contaminant, and their transformation behavior in water treatment processes has aroused great concern. In particular, toxic products might be produced during reaction with disinfectants during the disinfection process. As one of the most widely used UV filters, oxybenzone has received significant attention, because its transformation and toxicity changes during...
