Common oxidants activate the reactivity of zero-valent iron (ZVI) and hence remarkably enhance nitrate reduction from water

Kinetic and mechanistic analysis of azo dyes decolorization by ZVI-assisted Fenton systems: pH-dependent shift in the contributions of reductive and oxidative transformation pathways

“…It should be taken into account that the behavior of ZVI/H2O systems is conditioned by the fact that Fe(II) may be further oxidized yielding Fe(III). Ferric species are rather insoluble above pH 4 and their precipitation usually leads to the formation of a corrosion layer (CL) onto the surface of ZVI particles [16,17]. The oxidation of Fe(0) initially yields a large array of porous hydroxides which are further transformed into less porous oxides by dehydration [15].…”

The mechanism for bacteriophage f2 removal by nanoscale zero-valent iron

“…Obviously, the removal efficiency was much higher in aerobic systems than that in anaerobic ones. The process was mainly related to the oxidation of zero-valent iron, which improved the removal efficiency of contaminants Guo et al, 2015). In addition, the removal rate went up as the dosage of NZVI increased no matter under anaerobic or aerobic conditions.…”

Degradation of aquatic sulfadiazine by Fe0/persulfate: kinetics, mechanisms, and degradation pathway

“…(5)). Besides, Guo et al 12,32 rstly reported that common oxidants could enhance the reactivity of Fe 0 by cleaning the precipitation of ferric hydroxides at the Fe 0 surface. Lai et al 33,34 also reported that the PS could accelerate the reductive rate of 4-nitrophenol by Fe 0 .…”
