Summary: This research explores the potential use of pyrite cinder as a Fenton-like catalyst for removing Reactive Red 120 from water. The PC demonstrated excellent catalytic properties in a heterogeneous Fenton system. Optimal conditions for decolorization were found to be a reaction time of 480 min, RR120 concentration of 50 mg/L, PC dosage of 4 g/L, H2O2 concentration of 10 mM, and pH of 3. The efficiency of metal leaching and detoxification of the effluent was assessed, as well as the formation of degradation products. The study provides an effective method for removing azo dye from polluted water using waste tailings as catalysts.

Summary: The development of highly active and stable catalytic materials for heterogeneous photo-Fenton-like (HPF-like) process has gained significant attention due to the increasing demands for water purification worldwide. Oxygen vacancies (OVs) modulation is a prevalent strategy to enhance the performance of heterogeneous catalysts. In this study, polyvinylpyrrolidone (PVP) modified CuFeO2 (PVP/CFO) catalysts were prepared for the degradation of ofloxacin (OFX) in HPF-like process. The introduction of PVP resulted in rich OVs and more Fe2+ active sites on PVP/CFO surface, while inhibiting the aggregation of CuFeO2 particles. The PVP/CFO-4 catalyst with 4 g of PVP showed superior catalytic performance for OFX degradation and good stability in the HPF-like system. The introduced OVs and photoelectron generated on PVP/CFO effectively accelerated the in situ recycling of Cu2+/Cu+ and Fe3+/Fe2+, promoting the formation of center dot OH/center dot O2- and OFX mineralization. The primary active species for OFX degradation were identified as center dot OH, center dot O2-, and e-, with h+ serving as an auxiliary species. Density functional theory calculation and liquid chromatography mass spectrometry were used to propose the OFX degradation pathways, and the overall toxicity of intermediates was reduced after HPF-like degradation based on quantitative structure-activity relationship predictions.

Summary: The selective decolorization of mixed dyestuffs was achieved using a heterogeneous catalyst. Cu/Fe@biochar composites with varying amounts of copper and iron were prepared and showed excellent catalytic performance in degrading methyl orange and methylene blue. The composite with the highest metal component (294.44 mg/g iron and 16.22 mg/g copper) could decolorize 97.35% of methyl orange in 60 minutes and 100% of methylene blue in 10 minutes. The selectivity of the degradation was influenced by competitive adsorption and the phase where the dyestuffs were degraded, and depended on the catalyst's performance.

Summary: The study showed that weak magnetic field can enhance the degradation efficiency of orange G by the Fe3O4/H2O2 magnetic Fenton system, primarily by increasing the production of hydroxyl radicals. This improvement was attributed to the acceleration of Fe3O4 corrosion rate by the presence of weak magnetic field, which led to increased release of Fe(II) and enhanced degradation of the dye.

Summary: In this study, the performance and mechanism of Fenton-like process catalyzed by pyrite were investigated. It was found that homogeneous reactions played a major role in naphthalene degradation in the H2O2/pyrite system. The sulfur species in pyrite facilitated the iron redox cycle and the production of reactive oxygen species, thereby enhancing the degradation efficiency of naphthalene. Pyrite exhibited higher reaction efficiency and lower cost compared to other iron-containing minerals, and showed excellent performance in various water environments for pollutant removal.

Summary: This study investigated the abiotic transformations of the antibiotic sulfamethoxazole (SMX) by intermediates produced during biological nitrogen removal processes, including hydroxylamine (NH2OH), nitrite (NO2-), and nitric oxide (NO). The results showed that while NH2OH was not directly able to transform SMX, NO2- and NO could chemically transform SMX through various reactions. The study also determined the rate constants of SMX with NO2- and NO under different pH and oxygen conditions. The findings enhance our understanding of antibiotic fate during biological nitrogen removal and emphasize the role of reactive nitrogen species in antibiotic degradation.

Summary: In order to enhance the utilization of peroxymonosulfate (PMS) and the stability of catalyst, a dual-reaction center catalyst Cu-Mg0.388Al2.408O4-BN was developed without expensive rare metals. The presence of Mg resulted in a positively charged surface, which facilitated the adsorption of bisphenol A (BPA) and PMS anions under neutral pH conditions. The formation of an electron-rich Cu center was achieved due to the relatively low electronegativity of Mg and the cation-pi interaction between Cu and boron nitride (BN). The combination of electrostatic attraction and dual-reaction center enabled the rapid degradation of BPA through electron transfer and subsequent activation of PMS.

Summary: In this study, the complete defluorination of PFOA using ultrasound/persulfate (US/PS) was investigated, and 100% defluorination was achieved after 4 hours of ultrasound treatment alone. The addition of persulfate suppressed defluorination, possibly due to the increased competition with PFOA for adsorption sites. The study also challenges the previous understanding that defluorination occurs at the bubble-water interface.

Summary: This study investigated the CO3·-mediated oxidation of the frequently detected micropollutant ibuprofen. The results showed that the H atom abstraction pathway dominated the degradation process, regardless of the protonation state. Calculation of the reaction rate constant considering explicit solvent molecules yielded a value in agreement with the measured one. Significant charge transfer was observed from the CO3 center to the solvation shells. The study also constructed a contour plot demonstrating the contribution of CO3·- to the elimination of various micropollutants, highlighting the importance of CO3·- in sunlit surface waters.

Summary: Urbanization and industrialization have negatively impacted water quality, leading to a demand for reliable and eco-friendly treatment technologies. Persulfate-based advanced oxidation processes (AOPs) have shown promise in treating challenging industrial wastewaters and remediating contaminated groundwater. Comparisons of reaction rate constants for different pathways suggest that radical-based AOPs can achieve high removal efficiency with short contact times, while nonradical AOPs are advantageous for complex wastewater treatments with minimal interference. However, nonradical pathways require significantly higher energy requirements. These comparisons inform the prioritization of basic research and the understanding of system-specific application merits and limitations.

A Z-scheme plasmonic photocatalyst Bi-CeO2/Ag-0/BiO2 was designed and fabricated to activate dissolved oxygen in water for micropollutant degradation under visible light. The doped Bi improved the separation of electron-hole and narrowed the band gap of CeO2, while metallic silver (Ag-0) acted as an electronic transmission vehicle in a Z-scheme mechanism.

By modifying and improving the existing equations for soil texture and permeability, the study successfully included information on saturated hydraulic conductivity (Ksat) into the calculation of K factor. Using the Random Forest machine learning algorithm, two independent K factor maps with different spatial resolutions were generated. The results show that the decrease in K factor values has a positive impact on the modeling of soil erosion rates.

The study found that both the mass concentration of PM2.5 and the DTT activity were higher during the heating season than during the nonheating season. Combustion sources were the primary contributors to DTT activity during the heating season, while secondary formation dominated during the nonheating season. The study also revealed that biomass burning had the highest inherent oxidation potential among all sources investigated.

Aluminum was found in tumor areas of 24% of patients and was associated with epithelial to mesenchymal transition (EMT) and cell death. Additional analyses revealed higher tumor mutational burden and mutations in genes related to EMT and apoptosis in aluminum-positive colon cancers. Understanding the molecular mechanisms of aluminum toxicity may improve strategies for the management of colon cancer patients.
