It has been shown that numerous inorganic and organic
micropollutants can be transformed by chlorine. However, for
certain compounds, the chlorine reactivity is low and only
small modifications in the parent compound’s structure are
expected under water treatment conditions.
During chlorination processes, HOCl is generally the major
reactive species for the reaction with micropollutants. A pH
dependence of organic and inorganic micropollutant transformation
is commonly observed due to chlorine speciation
in solution.
