Herein, we proposed a new peroxymonosulfate (PMS) activation system employing the Fe(III) doped g-C3N4 (CNF) as catalyst. Quite different from traditional sulfate radical-based advanced oxidation processes (SR-AOPs), PMS/CNF was capable of selectively degrading phenolic compounds (e.g., p-chlorophenol, 4-CP) in wide pH range (3–9) via nonradical pathway. The generated singlet oxygen (1O2) PMS/CNF3 (3.46 wt % Fe) played negligible role removing 4-CP, and high-valent iron-oxo species fixated...
Significance In the bulk phase, hydroxyl radical from one-electron transfer and high-valent iron-oxo species O-atom compete to be reactive intermediates in Fenton related reactions. confined space at a nanoscale, however, behavior of reaction is elusive. Herein, we report an unprecedented singlet oxygen mediated Fenton’s occurred inside carbon nanotube with inner diameter ∼7 nm, showing exotic catalytic activities, unforeseen adsorption-dependent selectivity, pH stability for oxidation...
Oxygen vacancies (OVs) play a crucial role in the catalytic activity of metal-based catalysts; however, their activation mechanism toward peroxydisulfate (PDS) still lacks reasonable explanation. In this study, by taking bismuth bromide (BiOBr) as an example, we report OV-mediated PDS process for degradation bisphenol A (BPA) employing singlet oxygen (1O2) main reactive species under alkaline conditions. The experimental results show that removal efficiency BPA is proportional to number OVs...
A new nanocomposite adsorbent La-201 of extremely high capacity and specific affinity toward phosphate was fabricated well characterized, where hydrated La(III) oxide (HLO) nanoclusters were immobilized inside the networking pores polystyrene anion exchanger D-201. exhibited enhanced adsorption in presence competing anions (chloride, sulfate, nitrate, bicarbonate, silicate) at greater levels (up to molar ratio 20), with working 2-4 times higher than a commercial Fe(III) oxide-based HFO-201...
Sulfidation has gained increasing interest in recent years for improving the sequestration of contaminants by zerovalent iron (ZVI). In view bright prospects sulfidated ZVI (S-ZVI), this review comprehensively summarized latest developments sulfidation ZVI, particularly that nanoscale (S-nZVI). The milestones development S-ZVI technology including its background, enlightenment, synthesis, characterization, water remediation and treatment, etc., are summarized. Under most circumstances, can...
When zerovalent iron (ZVI) is used in reductive removal of contaminants from industrial wastewater, where dissolved oxygen (DO) competes with target contaminant for the electrons donated by ZVI, both reactivity and electron selectivity (ES) ZVI toward are critical. Thus, ES two sulfidated (S-ZVI) samples, synthesized ball-milling elemental sulfur (S-ZVIbm) reacting Na2S (S-ZVINa2S), Cr(VI) under aerobic conditions were investigated. Sulfidation appreciably increased ratio rate constants...
The presence of diverse pollutants in water has been threating human health and aquatic ecosystems on a global scale. For more than century, chemical oxidation using strongly oxidizing species was one the most effective technologies to destruct ensure safe clean supply. However, removal increasing amount with higher structural complexity, especially emerging micropollutants trace concentrations complicated matrix, requires excessive dosage oxidant and/or energy input, resulting low...
Here we fabricated a novel nanocomposite HZO-201, an encapsulated nanosized hydrous zirconium oxide (HZO) within commercial porous polystyrene anion exchanger D201, for highly efficient defluoridation of water. HZO-201 exhibited much higher preference than activated alumina and D201 toward fluoride removal when competing anions (chloride, sulfate, nitrate, bicarbonate) coexisted at relatively high levels. Fixed column adsorption indicated that the effective treatable volume water with was...
The simultaneous reduction and sequestration of Cr(VI) from wastewater is desirable as a cost-effective environmentally friendly approach. In this study, we execute one-step facile synthesis strategy on polyaniline (PANI) composites based aniline adsorption polymerization pores millimeter-scale polystyrene balls (PANI@PS). well-defined PANI@PS increased the removal capacity by 5.4 times, going 43.6 (bulky PANI) to 233.7 mg g-1 near neutral pH (6.0) instead 1-3 documented in other reports,...
