Ferrate(VI)/Periodate System: Synergistic and Rapid Oxidation of Micropollutants via Periodate/Iodate-Modulated Fe(IV)/Fe(V) Intermediates

Environmental Science & Technology, Journal Year: 2023, Volume and Issue: 57(17), P. 7051 - 7062

Published: April 19, 2023

The presence of organic micropollutants in water sources worldwide has created a need for the development effective and selective oxidation methods complex matrices. This study is first report combination ferrate(VI) (Fe(VI)) periodate (PI) synergistic, rapid, elimination multiple micropollutants. combined system was found to outperform other Fe(VI)/oxidant systems (e.g., H2O2, peroxydisulfate, peroxymonosulfate) rapid decontamination. Scavenging, probing, electron spin resonance experiments showed that high-valent Fe(IV)/Fe(V) intermediates, rather than hydroxyl radicals, superoxide singlet oxygen, iodyl played dominant role process. Further, generation evidenced directly by 57Fe Mössbauer spectroscopic test. Surprisingly, reactivity PI toward Fe(VI) low (0.8223 M-1 s-1) at pH 8.0, implying not acting as an activator. Besides, only iodine sink PI, iodate also enhanced micropollutant abatement oxidation. Further proved and/or might function ligands, causing utilization efficiency intermediates pollutant outcompete their auto-decomposition. Finally, oxidized products plausible transformation pathways three different single Fe(VI)/PI were characterized elucidated. Overall, this proposed novel strategy (i.e., system) could efficiently eliminate clarified unexpected interactions between PI/iodate accelerated
