Mechanistic Insight into the Reactivity of Chlorine-Derived Radicals in the Aqueous-Phase UV–Chlorine Advanced Oxidation Process: Quantum Mechanical Calculations", Environ. Sci. Technol. 2017, 51, 12, 6918–6926

The combined ultraviolet (UV) and free chlorine (UV–chlorine) advanced oxidation process that produces highly reactive hydroxyl radicals (HO^•) and chlorine radicals (Cl^•) is an attractive alternative to UV alone or chlorination for disinfection because of the destruction of a wide variety of organic compounds.
