A Novel Source of Radicals from UV/Dichloroisocyanurate for Surpassing Abatement of Emerging Contaminants Versus Conventional UV/Chlor(am)ine Processes

Environmental Science & Technology, Journal Year: 2023, Volume and Issue: 57(47), P. 18452 - 18461

Ultraviolet (UV)/chlor(am)ine processes are emerging advanced oxidation (AOPs) for water decontamination and raising continuous attention. However, limitations appear in the UV/hypochlorite UV/monochloramine removing specific contaminants ascribed to differences sorts yields of free radicals. Here, this study reports UV/dichloroisocyanurate (NaDCC) as a novel source NaDCC was demonstrated be well-balanced compound between hypochlorite monochloramine, it had significant UV absorption medium intrinsic quantum yield. The UV/NaDCC produced more substantial hydroxyl radicals (·OH) reactive chlorine species (RCSs, including Cl·, ClO·, Cl2·-) than conventional UV/chlor(am)ine, thereby generating higher efficiency. reaction mechanisms, environmental applicability, energy requirements process (ECs) abatement were further investigated. results showed that ·OH ·NH2 attacked ECs mostly through hydrogen atom transfer (HAT) radical adduct formation, whereas Cl· destroyed mainly HAT single electron transfer, with ClO· playing certain role HAT. Kinetic model analyses revealed outperformed UV/chlor(am)ine variety matrices superior degradation efficiency, significantly saving up 96% electrical per order. Overall, first demonstrates application prospects AOP using UV/NaDCC, which can compensate deficiency AOPs.
