“…Similarly with AMO degradation, low mineralization in electrolysis alone process resulted from the mass transfer limitation of AMO molecules to the anode surface as described for the low Please do not adjust margins Please do not adjust margins degradation degree 19,30 . As for ozonation, although O 3 could completely destruct the AMO structure in 5 min, it reacted rarely with the aliphatic carboxylic acids formed from the oxidation intermediates 33,34 . In the long time mineralization of AMO, the •OH production in E-peroxone seemed to play an important role.…”

Amoxicillin (AMO) degradation was investigated using electrolysis, ozonation, and electro-peroxone (E-peroxone) process. E-peroxone process was found to be the most effective for AMO degradation. 67.8% total organic carbon (TOC) mineralization was obtained after 60 min by E-peroxone process. In comparison, only 47.3% and 3.1% TOC mineralization were obtained using individual ozonation and electrolysis process, respectively. It was found that hydroxyl radical production and O3 utilization were both enhanced in E-peroxone process. The effect of pH on E-peroxone process was investigated, and the highest AMO removal rate was obtained at pH= 9, indicating pH control was crucial in E-peroxone process. In addition, more oxidation typical intermediates were identified in E-peroxone process than ozonation process using UPLC-MS/MS. Different pathways of AMO degradation were proposed, involving the hydroxylation of the benzoic ring and N, the four-membered β-lactamic ring opening, the oxidation of S, and other bond cleavage reactions. All these results above indicated that the introduction of electrolysis in ozonation has enhanced AMO cleavage and hence its degradation.

“…These facts have encouraged recent investigation on effective treatment methods to remove IBP in aqueous phase, such as sonication [21,22], ozonation [23], photo-Fenton [24], photolysis [9], heat-activated persulfate [8] and photocatalysis [25]. In the last decade, sulfate radicals (SO 4 ÅÀ )-based oxidation technologies have attracted increasing interests [26][27][28][29].…”

“…Chemical degradation treatments of ibuprofen known as Advanced Oxidation Processes (AOPs) were performed using ozonization (Quero-Pastor et al, 2014), ultrasound wave "sonolysis" (Méndez-Arriaga et al, 2008) pulse radiolysis (Illés et al, 2013), Fenton reaction and photo-Fenton (Sabri et al, 2012).…”
