Identification of halogenated compounds produced by chlorination of humic acid in the presence of bromide
article
The formation of halogenated compounds by chlorination of humic acid with and without bromide present was compared. The presence of bromide ion results in the production of many brominated and mixed bromo-chloro compounds. Trihalomethanes, halogenated aliphatic acids and diacids, and trihalomethane precursors are major products. The presence and identity of the halogenated compounds were also confirmed by the use of an atomic emission detector. The mutagenic activity was determined and shown to be 2-3 times higher when bromide is present during chlorination. Chemicals/CAS: humic acid, 1415-93-6
