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
