Abstract
The UV/chlorine process is an emerging advanced oxidation process (AOP) used for the degradation of micropollutants. However, the radical chemistry of this AOP is largely unknown for the degradation of numerous structurally diverse micropollutants in water matrices of varying quality. These issues were addressed by grouping 34 pharmaceuticals and personal care products (PPCPs) according to the radical chemistry of their degradation in the UV/chlorine process at practical PPCP concentrations (1 μg L–1) and in different water matrices. The contributions of HO• and reactive chlorine species (RCS), including Cl•, Cl2•–, and ClO•, to the degradation of different PPCPs were compound specific. RCS showed considerable…
