Degradation kinetics and mechanism of β-lactam antibiotics by the activation of H2O2 and Na2S2O8 under UV-254nm irradiation
He, Xuexiang; Mezyk, Stephen P.; Michael, Irene; Fatta-Kassinos, Despo; Dionysiou, D. D. (2014)The extensive production and usage of antibiotics have led to an increasing occurrence of antibiotic residuals in various aquatic compartments, presenting a significant threat to both ecosystem and human health. This study ...

Kinetic and mechanism investigation on the photochemical degradation of atrazine with activated H2O2, S2O82− and HSO5−
Khan, Javed Ali; He, Xuexiang; Shah, Noor S.; Khan, Hasan M.; Hapeshi, E.; Fatta-Kassinos, Despo; Dionysiou, D. D. (2014)•Degradation of atrazine was investigated in UV, UV/H2O2, UV/HSO5− and UV/S2O82− AOPs.•UV/S2O82− process was found to be more efficient as well as more economical.•The pH affected UV/S2O82− but had no significant influence ...

Significant role of UV and carbonate radical on the degradation of oxytetracycline in UV-AOPs: Kinetics and mechanism
Liu, Yiqing; He, Xuexiang; Duan, X.; Fu, Yongsheng; Fatta-Kassinos, Despo; Dionysiou, D. D. (2016)Carbonate radical (CO3•-), a selective oxidant, reacts readily with electron-rich compounds through electron transfer and/or hydrogen abstraction. In this study, the role of CO3•- in degrading oxytetracycline (OTC) by UV ...
