Theoretical insights into the degradation of tyrosol stimulated by hydroxyl and sulfate radicals in wastewater and ecotoxicity evaluation

The photochemical degradation of tyrosol (TY) in wastewater was investigated by theoretical method. The highly oxidative radicals (⋅OH and SO4•-) were employed to study the TY transformation behaviors and kinetic properties. The ⋅OH-addition and H-abstraction reaction mechanisms were predominant for ⋅OH and SO4•--initiated reactions, respectively. The rate constants of TY + ⋅OH and TY + SO4•- systems were determined as 9.15 × 109 M−1 s−1 and...
