Current Status of Emerging Contaminant Models and Their Applications Concerning the Aquatic Environment: A Review

Water, Год журнала: 2025, Номер 17(1), С. 85 - 85

Опубликована: Янв. 1, 2025

Increasing numbers of emerging contaminants (ECs) detected in water environments require a detailed understanding these chemicals’ fate, distribution, transport, and risk aquatic ecosystems. Modeling is useful approach for determining ECs’ characteristics their behaviors environments. This article proposes systematic taxonomy EC models addresses gaps the comprehensive analysis applications. The reviewed include conventional quality models, multimedia fugacity machine learning (ML) models. Conventional have higher prediction accuracy spatial resolution; nevertheless, they are limited functionality can only be used to predict contaminant concentrations Fugacity excellent at depicting how travel between different environmental media, but cannot directly analyze variations parts same media because model assumes that constant within compartment. Compared other ML applied more scenarios, such as identification assessments, rather than being confined concentrations. In recent years, with rapid development artificial intelligence, surpassed becoming one newest hotspots study ECs. primary challenge faced by outcomes difficult interpret understand, this influences practical value an some extent.

Mechanistic insights into the enhanced photocatalytic efficiency of MoS₂-tuned DyFeO₃ heterojunction for pollutants degradation

Nanoscale, Год журнала: 2025, Номер unknown

Опубликована: Янв. 1, 2025

In this study, DyFeO3-MoS2 heterojunction nanocomposites were synthesized by integrating porous DyFeO3 nanoparticles (an n-type semiconductor) with MoS2 nanosheets (a p-type semiconductor). The resulting p-n substantially improved the photocatalytic efficiency for degrading methylene blue (MB) and levofloxacin (LFX). This design introduces a built-in electric field at interface, promoting efficient charge separation suppressing electron-hole recombination, thereby significantly enhancing performance under solar irradiation compared to alone. Characterization studies, including XRD, FESEM, TEM, XPS, UV-visible absorbance, photoluminescence, Mott-Schottky analysis, confirmed nanocomposites' crystalline structure, well-dispersed nanosheets, oxygen vacancies, enhanced visible light absorption, favorable band positions. incorporation of increased separation, surface area mitigating aggregation, leading higher degradation rates. Among tested compositions, (80 : 20) nanocomposite, containing 20 wt% MoS2, exhibited highest efficiencies, 96.5% MB 88.7% LFX. Further analyses, activation energy determination, quantum yield measurement, scavenger tests, reusability assessments, optimized nanocomposite's durability. reduced energies high yields (35.5% MB, 25.8% LFX) indicate photon conversion radical generation, superoxide radicals (˙O2-) identified as primary reactive species. Stability tests revealed over 85% retention activity after four cycles, underscoring composite's robustness. Moreover, mechanism key insights into pathways pollutants. investigation demonstrates viable solar-driven solution pollutant in wastewater treatment incorporating nanostructures.
