The reactions between peroxymonosulfate (PMS) and quinones were investigated for the first time in this work, where benzoquinone (BQ) was selected as a model quinone. It demonstrated that BQ could efficiently activate PMS degradation of sulfamethoxazole (SMX; frequently detected antibiotic environments), rate increased with solution pH from 7 to 10. Interestingly, quenching studies suggested neither hydroxyl radical (•OH) nor sulfate (SO4•–) produced therein. Instead, generation singlet...
It is well documented that the traditional Fenton reagent (i.e., combination of Fe(II) and H2O2) produces hydroxyl radical (•OH) under acidic conditions, while at near-neutral pH reactive intermediate converts to ferryl ion (Fe(IV)) can oxidize sulfoxides produce corresponding sulfones, markedly differing from their •OH-induced products. However, it remains unclear whether Fe(IV) generated in activated peroxydisulfate (PDS) process, where sulfate (SO4•-) long recognized as dominant...
Recently, it has been reported that the combination of permanganate (Mn(VII)) and bisulfite can lead to a rapid degradation organic contaminants, where soluble Mn(III) is proposed be responsible. Interestingly, in this work, we demonstrated involvement high-valent Mn-oxo species (possibly Mn(V)) as well sulfate radical Mn(VII)/bisulfite system, by using methyl phenyl sulfoxide (PMSO) chemical probe. It was found Mn(VII) resulted appreciable PMSO under various conditions, while negligible...
Humic acid (HA) ubiquitously existing in aquatic environments has been reported to significantly impact permanganate (KMnO4) decontamination processes. However, the underlying mechanism of KMnO4/HA system remained elusive. In this study, an enhancing effect HA on KMnO4 oxidation diclofenac (DCF) was observed over a wide solution pH range 5–9. Surprisingly, HA-induced enhancement varied with pH. Quenching and chemical probing experiments revealed that manganese intermediates (Mn(III)-HA MnO2)...
The extensive use of bromophenols (BrPs) in industrial products leads to their occurrence freshwater environments. This study explored the oxidation kinetics several BrPs (i.e., 2-BrP, 3-BrP, 4-BrP, 2,4-diBrP, and 2,6-diBrP) potential formation brominated polymeric concern during water treatment with potassium permanganate [Mn(VII)]. These exhibited appreciable reactivity toward Mn(VII) maxima second-order rate constants (kMn(VII)) at pH near pKa values, producing bell-shaped pH-rate...
Recent studies have shown that manganese dioxide (MnO2) can significantly accelerate the oxidation kinetics of phenolic compounds such as triclosan and chlorophenols by potassium permanganate (Mn(VII)) in slightly acidic solutions. However, role MnO2 (i.e., an oxidant vs catalyst) is still unclear. In this work, it was demonstrated Mn(VII) oxidized trichloro-2-phenoxyphenol) its analogue 2-phenoxyphenol, mainly generating ether bond cleavage products 2,4-dichlorophenol phenol, respectively),...
In this work, the most widely used brominated flame retardant tetrabromobisphenol A (TBrBPA) was shown to exhibit appreciable reactivity toward potassium permanganate [Mn(VII)] in water over a wide pH range of 5–10 with maxima second-order rate constants (kMn(VII) = 15–700 M–1 s–1) at near its pKa values (7.5/8.5). novel precursor ion scan (PIS) approach using negative electrospray ionization-triple quadrupole mass spectrometry (ESI-QqQMS) adopted and further optimized for fast selective...
It is of great interest and big challenge to control the collective behaviors nanomotors mimic aggregation/separation behavior biological systems. Here, a light-acoustic combined method proposed artificial nanomotors. shown that aggregate at pressure node in acoustic field afterward present "firework" separation induced by light irradiation. The found be applicable for metallic materials polymers even different wavelengths are used. Physical insights on firework resulting from change...
In previous studies, we interestingly found that several ligands (e.g., pyrophosphate, nitrilotriacetate, and humic acid) could significantly accelerate the oxidation rates of triclosan (TCS; most widely used antimicrobial) by aqueous permanganate (Mn(VII)) especially at acid pH, which was ascribed to contribution ligand-stabilized Mn(III) (defined Mn(III)L) formed in situ as a potent oxidant. this work, it TCS Mn(III)L resulted formation dimers, well hydroxylated quinone-like products,...
In this work, the kinetics of transformation iodide (I–) and hypoiodous acid (HOI) by peroxymonosulfate (PMS) potential formation worrisome iodinated products in presence natural organic matter (NOM) were investigated. As pH increased from 5 to 10, apparent second-order rate constants reaction PMS with I– gradually decreased 1.01 × 103 3.86 102 M–1 s–1, while those for HOI dramatically 1.08 7.90 104 s–1. The obtained pH-dependent profiles explained well effects pH-affected speciation and/or...
