Molecular mechanisms and potential applications of the intrinsic chemiluminescence produced from the degradation of haloaromatic pollutants during environmentally-friendly advanced oxidation processes

Unprecedented ˙OH-dependent intrinsic chemiluminescence (CL) can be produced during the AOPs-mediated degradation of highly toxic haloaromatics (XAr), and a new CL analytical method was developed to measure XAr and monitor their degradation kinetics.
