Photo-electrooxidation treatment of Acetaminophen in aqueous solution using BDD-Fe and BDD-Cu systems

Heterogeneous Activation of Persulfate by Activated Carbon for Efficient Acetaminophen Degradation: Mechanism, Kinetics, Mineralization, and Density Functional Theory

“…Based on Figure 7 (b), there are two candidate sites for the attack of active radicals in hydroquinone C6 and C3, which leads to the formation of benzoquinone or leading to ring cleavages and produced carboxylic acid. For benzoquinone Figure 7(c), the active radicals attacked O 11 and 12 parallelly, which is due to the reverse reaction between benzoquinone and hydroquinone [42–44] . Figure 8 illustrated the proposed pathway of ACT degradation based on computational method…”

Application of photoelectrochemical oxidation of wastewater used in the cooling tower water and its influence on microbial corrosion

“…In the PO (S3) setup, the UV lamp was only used to treat the CTW (Marszałek and Puszczało, 2020 ; Yi et al, 2022 ). In the PEO (S4) process, the rod-shaped UV lamp (6W) (Heber) was inserted in the middle of the anode mesh (Sierra-Sánchez et al, 2022 ) as the control system without treatment (S1). The total working volume flowed through the peristaltic pump to prevent temperature rise (Elawwad et al, 2017 ).…”

“…One is direct oxidation, which occurs on the electrode surface, and it can be stopped by the electric field effect, hydroxyl radicals (OH), hydrogen peroxide, ozone, or hydrogen radicals (Anadebe et al, 2020 ). The formation of various aqueous solution oxidants, such as sulfate or chlorine species, is the foundation of the second strategy, known as indirect oxidation (Sierra-Sánchez et al, 2022 ). When applied correctly, the efficient processes of anodic oxidation (EO) and ultraviolet radiation (PO) can both reduce and eliminate pollutants found in wastewater (Ungureanu et al, 2020 ).…”

A review on the degradation of acetaminophen by advanced oxidation process: pathway, by-products, biotoxicity, and density functional theory calculation

“…Since the highest values (f À ) for 1,4-benzoquinone were (f À ¼ 0.188725) for O11 atom and (f À ¼ 0.188722) for O12 atom, in this case, the radical attack (O]C) bond for O11 and O12, resulting to reform of hydroquinone, this agreed with. 27,36,59,70 For pathway (ii) further oxidation of the small carboxylic acid leading to completely mineralization and produce CO 2 and H 2 O. Pathway (iii) more decomposition of carboxylic acid due to form small carboxylic acid such as glycolic acid, acetic acid, formic acid, pyruvic acid, oxalic acid, then convert to CO 2 and H 2 O. Fig.…”
