“…Moreover, as the dosages of TBA or EtOH increased from 200 to 600 mM, the curve began to show a stable trend as shown in Fig. 6 (Qi et al 2009;Xie et al 2015). It can be obtained from Fig.…”

The degradation kinetics and mechanism of the antiepileptic drug oxcarbazepine (OXC) by UV-activated persulfate oxidation were investigated in this study. Results showed that UV/persulfate (UV/PS) process appeared to be more effective in degrading OXC than UV or PS alone. The OXC degradation exhibited a pseudo-first order kinetics pattern and the degradation rate constants (k obs) were affected by initial OXC concentration, PS dosage, initial pH, and humic acid concentration to different degrees. It was found that low initial OXC concentration, high persulfate dosage, and initial pH enhanced the OXC degradation. Additionally, the presence of humic acid in the solution could greatly inhibit the degradation of OXC. Moreover, hydroxyl radical (OH•) and sulfate radical (SO4 (-)••) were identified to be responsible for OXC degradation and SO4 (-)• made the predominant contribution in this study. Finally, major intermediate products were identified and a preliminary degradation pathway was proposed. Results demonstrated that UV/PS system is a potential technology to control the water pollution caused by emerging contaminants such as OXC.

“…Many previous studies used TBA as the scavenger for hydroxyl radicals. Qi et al [22] reported that the ozonation of 2,4,6-trichloroanisole (TCA) catalyzed by the raw bauxite was strong inhibited in the presence of TBA. In this study, due to its relatively low reaction rate with sulfate radicals, higher removal of CBZ is achieved in the presence of TBA.…”

“…Several researches focused on catalyzed ozonation in the presence of solid metal oxides to remove recalcitrant pollutants [12]. In addition, catalyzed ozonation have already been used for taste and odor compounds removal from water [13][14][15][16]. High removal efficiency and convenient application of catalyzed ozonation for taste and odor removal had been obtained, but the reaction mechanism had not been clarified yet.…”
