Unraveling the multiple roles of VUV mediated hydroxyl radical in VUV/UV/chlorine process: Kinetic simulation, mechanistic consideration and byproducts formation

Disinfection of bromide-containing tryptophan water by UV/chlorine: brominated halonitromethane formation, impact factors, and pathways

“…[30][31][32] It has also been reported that RCSs are more selective to organic matter (e.g., purines, pyrimidines, and amino acids) that easily loses electrons compared to the HO˙radical. 28,33 Furthermore, Br − , which is ubiquitous in aqueous environments at concentrations of 24 to 1120 μg L −1 especially in seawater at approximately 65 mg L −1 , can induce the production of HBrO/OBr − with the existence of HClO/OCl − (eqn (7) and ( 8)), and the halogenating ability of HBrO is stronger than that of HClO. [34][35][36][37][38] Also, HBrO/OBr − can induce the production of bromate (BrO 3 − ) and reactive bromine species (RBSs) under UV conditions (eqn ( 9)-( 20)).…”
