Cyanuric acid (CA), a triazine-ring compound commonly used as stabilizer for free chlorine to enhance disinfection, often persists in wastewater the production of chlorinated cyanurates (Cl-CAs), posing challenges treatment. This study demonstrates that conventional advanced oxidation processes (UV/H2O2 and UV/peroxydisulfate) are ineffective degrading CA, while UV/sulfite system successfully achieves its breakdown. Hydrated electrons (eaq-) were identified primary reactive species responsible cleaving stable triazine ring, with minimal contributions from SO3•- H•. The pH value influences both activity eaq- degradability CA by altering structure; lower increases electron-deficient regions dihydrogen enhancing susceptibility nucleophilic attack eaq-. high concentrations Cl- can inhibit removal, likely due formation react sulfite suppress production. Effective degradation was also demonstrated real wastewater, highlighting sustainable solution water These findings offer valuable insights into transformation present effective approaches eliminating emerging contaminants context extensive use disinfectants.
