Optical Biosensors and Their Applications for the Detection of Water Pollutants

Biosensors, Journal Year: 2023, Volume and Issue: 13(3), P. 370 - 370

Published: March 10, 2023

The correct detection and quantification of pollutants in water is key to regulating their presence the environment. Biosensors offer several advantages, such as minimal sample preparation, short measurement times, high specificity sensibility low limits. purpose this review explore different types optical biosensors, focusing on biological elements principle operation, well recent applications water. According our literature review, 33% publications used fluorescence-based followed by surface plasmon resonance (SPR) with 28%. So far, SPR biosensors have achieved best results terms Although less common (22%), interferometers resonators (4%) are also highly promising due limits that can be reached using these techniques. In recognition elements, 43% published works focused antibodies affinity stability, although they could replaced molecularly imprinted polymers. This offers a unique compilation most work specific area biosensing for monitoring, both element transducer used, type target contaminant. Recent technological advances discussed.

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

Unveiling the Occurrence and Potential Ecological Risks of Organophosphate Esters in Municipal Wastewater Treatment Plants across China

Environmental Science & Technology, Journal Year: 2023, Volume and Issue: 57(5), P. 1907 - 1918

Published: Jan. 25, 2023

Organophosphate esters (OPEs) discharged from wastewater treatment plants (WWTPs) have attracted increasing concerns because of their potential risks to aquatic ecosystems. The identification the structures OPEs is a prerequisite for subsequent assessment environmental impacts, which could hardly be accomplished using traditional target analytical methods. In this study, we describe use suspect and nontarget screening techniques organophosphate triesters diesters (tri-OPEs di-OPEs) in influent effluent samples acquired 25 municipal WWTPs across China. There are totally 33 different OPE molecules identified, 11 detected first time 4 new public. all tested samples, di-OPEs account significant portion (53% on average) total (ng/L−μg/L). More importantly, most not eliminated after these WWTPs, while some even accumulate. research priority based ecological risk was also analyzed, results reflected previously unrecognized exposure emerging living organisms. These findings present holistic understanding relevance country scale, will hopefully provide guidance upgrade protocols modification governmental regulations future.
