Advanced oxidation processes (AOPs) based wastewater treatment - unexpected nitration side reactions - a serious environmental issue: A review

Chemical Engineering Journal, Journal Year: 2021, Volume and Issue: 430, P. 133002 - 133002

Published: Oct. 26, 2021

Chemical compounds containing nitro group (nitro-products) are a one of toxic by-products, that can be formed during wastewater treatment processes. In case presence nitrite or nitrate ions, the formation nitro-products advanced oxidation processes (AOPs) is very common. It caused by reactive nitrogen species (RNs) such as radical (NO3•), (NO2•), oxide (NO•) and peroxynirite (ONOO–). fact, oxidative degradation N-containing pollutants releases nitrate, ammonium ions. some cases, secondary reactions mineralised (nitrate ions) with parent intermediate compound generate next several nitro-products. The more comparing to primary act precursors nitrogenous disinfection by-products. Moreover, studies reported unexpected degradation. special attention should made monitor minimize these effects. De-nitration initial nitro-compounds induces various in AOPs. was observed for UV light driven, Fenton persulfate based sonochemical fixation key mechanism ultrasounds Therefore, this paper focused on comparison AOPs terms mechanisms associated environmental issues.

Graphitic Carbon Nitride-Based Heterojunction Photoactive Nanocomposites: Applications and Mechanism Insight

ACS Applied Materials & Interfaces, Journal Year: 2018, Volume and Issue: 10(25), P. 21035 - 21055

Published: June 1, 2018

The design of heterojunction with superior performance light absorption and appropriate conduction band valence potentials is a promising approach for the applications in efficient environmental remediation solar energy storage. In recent years, many studies have been devoted to graphitic carbon nitride (g-C3N4)-based photoactive nanomaterials under visible irradiation due its excellent physical, optical, electrical properties, which inspired us compile this review. Although reviews demonstrated about syntheses g-C3N4 composites, targeted review on systematic application photocatalytic mechanisms g-C3N4-based heterojunction, components are intimate linkage each other rather than physical mixture, still absent. review, storage, such as treatment persistent organic pollutants, heavy-metal-ion redox, oxidative decomposition pathogens, water splitting H2 evolution, CO2 reduction, systematically discussed. addition, some emerging applications, cells biosensors, also introduced. Meanwhile, comprehensive assessment basis first-principles calculations thermodynamics kinetics surface catalytic reaction electronic structure properties valued by end, brief summary perspectives designing practical showed bright future heterojunction. Altogether, complements information that previous frequently ignored points out development trends expected provide important references right directions nanomaterials.

ACS ES&T Engineering, Journal Year: 2021, Volume and Issue: 1(4), P. 725 - 752

Published: March 8, 2021

Electrified membranes (EMs) have the potential to address inherent limitations of conventional membrane technologies. Recent studies demonstrated that EMs exhibit enhanced functions beyond separation. Electrification could enhance performance and sustainability technologies stimulate new applications in water wastewater treatment. Herein, we first describe EM materials, synthesis methods, electrofiltration modules, operating modes. Next, highlight decontamination, purification, disinfection. Additionally, discuss state-of-the-art electrification methods for controlling organic fouling, biofouling, inorganic scaling. We also evaluate energy consumption treatment fouling control. conclude by discussing challenges improving stability practicality proposing pathways future research development. On basis our discussion, suggest may be viable ultrafiltration microfiltration but not salt-rejecting reverse osmosis nanofiltration applications. Further, find are promising decontamination control, these systems deployed fit-for-purpose distributed
