“…It is also well known that under-or over-dosing the photocatalyst load may lead to slow degradation [178,179]. In the case of the sono-chemical process, it has been proposed that the direct generation of hydroxyl radicals from water molecules without the use of intermediate species being capable of totally degrading some contaminants [175].…”

“…However, chlorine and hypochlorous acid were the dominant active chlorine species in acidic condition, and the standard redox potential of chlorine and hypochlorous acid were 1.36 and 1.49 V/SHE, respectively [18,51]. The standard redox potential of active chlorine species was far less than that of •OH (E8 5 2.80 V/SHE) [52].…”

To replace the high cost Pt anode, Ti based PbO2 electrode (PbO2‐Ti) and Ti based SnO2 doped with Sb electrode (SnO2/Sb‐Ti) were fabricated and compared for treating 0.1 mM Rhodamine B (RhB) in Electro‐Fenton (EF) process. Scanning electron microscopy, energy dispersive X‐ray, X‐ray diffraction spectrometry were carried out to study the surface morphology, element composition, and substance composition of the anodes (PbO2‐Ti and SnO2/Sb‐Ti). Linear Sweep Voltammetry, cyclic voltammetry, Tafel, and electrochemical impedance spectroscopy were conducted to examine the electrochemical properties of the anodes (Pt, PbO2‐Ti, SnO2/Sb‐Ti, and Ti). These assessments showed that PbO2‐Ti had the best performance. Then, the influence of varied parameters (pH, types of anodes, current density, and electrolyte) were explored. Almost complete decolorization (99.01%) was reached at pH 3, current density 50 A/m2, 0.05 M Na2SO4 using PbO2‐Ti as the anode after 20 min electrolysis. Under these conditions, 90.48% of total organic carbon was removed after 180 min. Finally, the durability of PbO2‐Ti was evaluated via accelerated service life test and exhibited long service lifetime (∼4000 h). © 2018 American Institute of Chemical Engineers Environ Prog, 38: 189–197, 2019

“…The removal of such types of semisynthetic acid-stable penicillin from contaminated soils and wastewaters is difficult to accomplish. The treatments of wastewater containing C 2019, 5, 68 2 of 11 antibiotics can be classified into biotic (biodegradation) [6] and nonbiotic (oxidation) processes [7]. Giraldo et al [6] evaluated various oxidation pathways with chloride ions to degrade oxacillin residues into biodegradable compounds.…”

Recycling Oxacillin Residues from Environmental Waste into Graphene Quantum Dots

Of great concern are the residual antibiotics from dirt that can be found in farm soil and wastewater. This kind of emerging pollutant into engineered nanomaterials is riveting. This work proposes the elimination and transformation of a beta-lactam antibiotic, oxacillin, from environmental waste to graphene quantum dots (GQDs). Two protocols were followed in which the use of ethylenediamine (EDA) in the transformation leads to GQDs with excellent optical properties. Therefore, two types of GQDs were synthesized in a Teflon-lined stainless autoclave by a thermal procedure using oxacillin in the absence and presence of EDA. The ensuing e-GQDs from oxacillin and EDA display a stronger fluorescence emission in comparison to those synthesized without EDA (o-GQDs). The combination of Kaiser test analyses, infrared (IR) and Raman measurements revealed the presence of oxygen-containing groups and primary amines at the edges of the graphitic nanolayer for e-GQDs. This straightforward strategy brings hope and opens a new interest in waste recycling by means of extracting residual contaminants from the environment for their further transformation into adequate non-toxic graphitic nanomaterials with potential applications.
