The objective of this study was to describe the complex chemistry of the
formation of chloro- and bromophenols during the chlorination of bromide- and phenol-containing
waters in order to define conditions that promote the formation of critical products
(2-bromophenol and 2,6-dibromophenol) under realistic drinking water treatment conditions.
Experimental approach is based on: a critical evaluation and compilation of existing second-order
rate constants for HOX-phenol reactions; determination of unknown second-order rate
constants for reactions of HOCl and HOBr with phenolic compounds over a wide pH range;
quantification of product distribution of the formed halophenols; and, formulation of a
kinetic model. This kinetic model enables us to investigate the influence of some water
quality parameters such as the concentration of phenol, ammonia, bromide and the pH on the
product distribution. Includes 7 references, table, figures.
