Periodate activation via metals and metal-based complexes: progress in degradation properties and mechanisms

Water Science & Technology, Journal Year: 2024, Volume and Issue: 90(5), P. 1681 - 1705

Published: Aug. 23, 2024

ABSTRACT Residuals of refractory organics in water create a deep hazard to the environment and human health, hence it is urgent develop efficient approaches remove organics. Being novel oxidizer, periodate (PI, IO4-) considered be stable advanced oxidation processes for degrading organics, such as antibiotics, dyes, pesticides, etc. Since activity PI alone low, necessary activate form active species effectively removing The studies activation via monometallic, bimetallic, metal oxides, complexes, etc., have obtained more concerns owing high efficiency decomposing However, no reviews related these been published recent years. This review summarized properties uses PI, analyzed degradation mechanisms various metals metal-based complexes activating highlighted limitations well future research directions.

Treatment of tetracycline in an aqueous solution with an iron–biochar/periodate system: Influencing factors and mechanisms

Water Science & Technology, Journal Year: 2024, Volume and Issue: 89(12), P. 3344 - 3356

Published: June 10, 2024

ABSTRACT In this study, a potassium ferrate (K2FeO4)-modified biochar (Fe–BC) was prepared and characterized. Afterwards, Fe–BC applied to activated periodate (PI) degrade tetracycline (TC), an antibiotic widely used in animal farming. The degradation effects of different systems on TC were compared the influencing factors investigated. addition, several reactive oxygen species (ROS) generated by Fe–BC/PI system identified, pathways analyzed. Moreover, reuse performance evaluated. results exhibited that could remove almost 100% under optimal conditions [BC] = 1.09 g/L, initial [PI] 3.29 [TC] 20.3 mg/L. Cl−, HCO3−, NO3−, humic acid inhibited varying degrees due their quenching ROS. degraded into intermediates even water carbon dioxide synergistic effect ROS Fe BC surface. reused four times, removal rate still maintained above 80%, indicating stable nature Fe–BC.

Visible Light-Assisted Periodate Activation Using Carbon Nitride for the Efficient Elimination of Acid Orange 7

Separations, Journal Year: 2024, Volume and Issue: 11(9), P. 274 - 274

Published: Sept. 19, 2024

The development of appropriate and effective periodate (PI) activation technology is currently a popular research area. This study presents novel efficient photocatalytic approach PI for pollutant degradation based on carbon nitride (g-C3N4) visible light (Vis). results show that the system can remove 92.3% acid orange 7 (AO7) within 60 min under g-C3N4/PI/Vis reaction system. rate constant (kobs) reached 4.08 × 10−2 min−1, which 4.21, 5.16 times, 51.3 times higher than g-C3N4/Vis (9.7 10−3 min−1), PI/Vis (7.9 min−1) g-C3N4/PI (7.96 10−4 respectively. Clearly, addition significantly enhances efficiency AO7 in Additionally, same conditions, presence showed excellent oxidation capacity photoactivation process compared with other common oxidants, such as peroxymonosulfate, peroxydisulfate, H2O2. Moreover, removal across wide range pH levels various anions. Electron paramagnetic resonance (EPR) quenching experiments suggested superoxide anions (•O2−) singlet oxygen (1O2) dominated pollutants In addition, catalyst relative stability during cyclic testing, although slight reduction was observed. brief, highly environmentally friendly, significant application potential wastewater treatment.
