Abstract: | A thermodynamic model for the inorganic, fast-reacting fraction of the total residual oxidant produced by chlorination in marine waters reveals that BrI species are more stable than ClI species. At typical amino-N levels, HOBr, NBr3, and NHBr2 predominate. Data on organic byproducts of chlorination generally support the model calculations. |
