Devising exceptional S-scheme heterojunction photocatalysts utilized in annihilating pharmaceuticals and chromium contamination is significant for addressing the problem of global water pollution. In this work, a chemically bonded Mn0.5Cd0.5S/BiOBr heterostructure with oxygen vacancies ingeniously developed through facile in-situ solvothermal synthesis. The designed exhibits eminently reinforced photo-activity destruction tetracycline hydrochloride Cr (VI) as compared its individual components. This substantial photo-redox performance amelioration benefitted from creation an intense internal electric field (IEF) via supplying powerful driving force migration highway by interfacial chemical bond to foster electron/hole disintegration. More intriguingly, IEF at hetero-interface drives fast consumption photo-induced holes Mn0.5Cd0.5S photoelectrons BiOBr, profoundly boosting enrichment active photo-carriers sparing photo-corrosion Mn0.5Cd0.5S. Furthermore, anti-interference property can work efficiently real matrices. Multiple uses recycled Mn0·5Cd0·5S/BiOBr evidence prominent robustness stability. achievement indicates vast potential photosystems structural defects design photo-responsive materials effective wastewater treatment.

Antibiotics are anthropogenic contaminants with a global presence and of deep concern in aquatic environments, while less is known about the occurrence risks their transformation products (TPs). Herein, we developed comprehensive suspect nontarget screening workflow based on high-resolution mass spectrometry to identify unknown antibiotic TPs wastewater treatment plant effluents. We identified 211 compounds (35 parent antibiotics 176 TPs) at confidence levels ≥3 107 originated from macrolides. were quantified by 17 standards semiquantified predicted response factors accounted for 55.6-95.1% (76.7% average) total concentrations parents TPs. 22.2%, 63.1%, 18.8% estimated be more persistent, mobile, toxic than antibiotics, respectively. Further ecological risk assessment toxicity organisms revealed that cumulative generally higher those parents. Despite newly formed N-oxide TPs, tertiary process (mainly ozonation) could decrease averaged 20.3% 36.2% antibiotic-related compounds. This study highlights necessity include environmental scrutiny different environments.

Effective management of water resources is crucial for global food security and sustainable development. In this Review, we explore the potential benefits challenges associated with treated wastewater (TW) reuse irrigation. Currently, 400 km3 yr−1 generated globally, but <20% treated, that TW, only 2–15% reused irrigation depending on region. The main limitation TW inability current treatment technologies to completely remove all micropollutants contaminants emerging concern, some which have unknown impacts crops, environment health. However, advanced schemes, supported by quality monitoring regulations, can provide a stable supply agricultural production, as demonstrated in regions such USA Israel. Such schemes could potentially serve net energy source, embedded exceeds needs 9 10 times. Agriculturally useful nutrients nitrogen, phosphorus potassium be also recovered reused. act major contributor circular economy development, first steps will funding implementation social acceptance. Treated alleviate imbalances boost production water-scarce regions, thus promoting security. This Review discusses widespread agriculture framework.

Preparation of NH2-MIL-101(Fe) Metal Organic Framework and Its Performance in Adsorbing and Removing Tetracycline

International Journal of Molecular Sciences, Год журнала: 2024, Номер 25(18), С. 9855 - 9855

Опубликована: Сен. 12, 2024

Tetracycline’s accumulation in the environment poses threats to human health and ecological balance, necessitating efficient rapid removal methods. Novel porous metal–organic framework (MOF) materials have garnered significant attention academia due their distinctive characteristics. This paper focuses on studying adsorption performance of amino-modified MIL-101(Fe) towards tetracycline, along with mechanisms. The main research objectives conclusions are as follows: (1) NH2-MIL-101(Fe) MOF were successfully synthesized via solvothermal method, confirmed through various characterization techniques including XRD, FT-IR, SEM, EDS, XPS, BET, TGA. (2) exhibited a 40% enhancement tetracycline compared MIL-101(Fe), primarily chemical following pseudo-second-order kinetics. process conformed well Freundlich isotherm models, indicating multilayer heterogeneous Thermodynamic analysis revealed spontaneous endothermic reaction. (3) An increased adsorbent dosage temperature correspondingly improved NH2-MIL-101(Fe)’s efficiency, optimal observed under neutral pH conditions. These findings provide new strategies for effective from environment, thus holding implications environmental protection.

Despite Australia's high antimicrobial use, their residues in wastewater and impacts on receiving waters remain largely unknown. This study assessed the occurrence, removal, risk for resistance (AMR) of 102 substances selected transformation products (TPs) effluent from 47 treatment plants (WWTPs) across Australia. Thirty-two antimicrobials 13 TPs were detected, with 14 analytes occurring at >80% frequencies. Ampicillin, penicillin V, penicilloic V acid, fluconazole, tazobactam M1 observed median concentrations >0.2 μg/L. Collectively, WWTPs released 5.4 kg/day or 0.54 g/day/1000 inhabitants antimicrobials/TPs into natural waters, β-lactams, quinolones, nitroimidazoles/azoles, sulfonamides comprising volumes, which was correlated population's socioeconomic statuses. Thirty-seven removed rates post-treatment, whereas lincosamides, macrolide poor removal efficiencies, affected by processes regional climate. Comparing measured predicted no-effect AMR selection (PNECAMR), 7 exerted resistant bacteria. Concerningly, ciprofloxacin posed medium/high most WWTPs. The accumulative effects classes certain might further aggravate adverse development. Our provides insights presence implications treated wastewater, aiming to safeguard public health ecosystems.
