Transition metal doped g-C₃N₄ composites have been proved as promising photo-Fenton catalysts for degrading organic pollutants. The efficient coordination between transition metal ions and nitrogen atoms is crucial to the preparation of transition metal doped g-C₃N₄ composites. However, it is a challenge to ensure the high coordination efficiency of transition metal ions in g-C₃N₄. In this work, two series of monometallic doped Co_x-g-C₃N₄ and bimetallic doped Co_1.2Fe_y-g-C₃N₄ composites were synthesized by employing two transition metal-based deep eutectic solvents (DESs) as reaction media. The mild ionothermal conditions provided a favorable environment for doping transition metal ions in g-C₃N₄. After annealing these composites, the as-formed Co_x-CN and Co_1.2Fe_y-CN composites displayed excellent photo-Fenton activities for degrading organic dyes and antibiotics. Moreover, compared with Co_x-CN, Co_1.2Fe_y-CN exhibited enhanced photo-Fenton activities. This research might offer a new approach for preparing transition metal doped g-C₃N₄ composites in DESs.

Rational design of S-scheme AgI/ZrTiO_4-x heterojunctions for remarkably boosted norfloxacin degradation was written by Xin, Changhui;Zhu, Songwei;Liao, Jinyi;Hou, Mingming;Li, Qian;Yu, Xin;Li, Shijie. And the article was included in Chemosphere in 2022.Formula: C16H18FN3O3 The following contents are mentioned in the article:

Emerging S-scheme heterojunction photocatalysts endowed with efficient charge separation and strong redox capacity have stimulated wide interests in dealing with environmental issues nowadays. In this work, we firstly fabricated the oxygen vacancy modified ZrTiO_4-x nanocrystals, which was further combined with AgI to build the defective S-scheme AgI/ZrTiO_4-x heterojunctions for visible-light photocatalytic norfloxacin degradation The synthesized ZrTiO_4-x nanocrystals and AgI/ZrTiO_4-x heterojunctions displayed remarkably boosted norfloxacin degradation performance under visible-light irradiation The reaction rate constant of the optimized AgI/ZrTiO_4-x-5% heterojunction is as high as 0.01419 min-1, which is approx. 43.35 times that of AgI and 7.93 times that of ZrTiO_4-x nanocrystals, and far superior to those of com. TiO₂ and com. ZrO₂. The high-performance photocatalytic norfloxacin degradation could be mainly attributed to the formation of S-scheme charge transfer pathways and oxygen vacancy defects. More significantly, AgI/ZrTiO_4-x could also realize the effective photo-decomposition of other emerging pollutants. Finally, the visible-light photocatalytic performance and photocatalysis mechanism were investigated.

TiO₂-immobilized porous geopolymer composite membrane for removal of antibiotics in hospital wastewater was written by Sanguanpak, Samunya;Shongkittikul, Witaya;Saengam, Chitsuphang;Chiemchaisri, Wilai;Chiemchaisri, Chart. And the article was included in Chemosphere in 2022.Safety of 1-Ethyl-6-fluoro-4-oxo-7-(piperazin-1-yl)-1,4-dihydroquinoline-3-carboxylic acid The following contents are mentioned in the article:

This exptl. research proposes an environment-friendly and low-cost porous geopolymer composite membrane (PGCM) to treat antibiotics in hospital wastewater. The proposed PGCM consisted of two layers: a porous support layer and a dense coating layer. The dense coating layer was synthesized by incorporating variable TiO2 content (0, 2, 6, and 10 wt%) into the geopolymer matrix. The dense coating layer was of hierarchical mesoporous structure with 700μm in thickness and adhered to the porous support layer. The average pore size, total pore volume, and open porosity of the dense coating layer decreased with an increase in TiO₂, resulting in reduced water permeability. The PGCM was applied to remove six target antibiotics including amoxicillin, ciprofloxacin, norfloxacin, sulfamethoxazole, tetracycline, and trimethoprim in real hospital wastewater. By comparison, the PGCM with 10 wt% TiO2 achieved the highest antibiotic removal efficiencies, with the adsorption and combined adsorption/photodegradation removal efficiencies for the target antibiotics of 38-75% and 74-86%, resp. The novelty of this research lies in the use of a tailor-made porous geopolymer composite membrane incorporated with TiO₂ photooxidation as a single-step treatment of recalcitrant antibiotics contained in hospital wastewater.

Source-specific ecological risks and critical source identification of PPCPs in surface water: Comparing urban and rural areas was written by Wu, Yanqi;Song, Shuai;Chen, Xinchuang;Shi, Yajuan;Cui, Haotian;Liu, Ying;Yang, Shengjie. And the article was included in Science of the Total Environment in 2023.Synthetic Route of C16H18FN3O3 The following contents are mentioned in the article:

To control the concentrations of pharmaceutical and personal care products (PPCPs) in the surface water of urban and rural areas, it is important to explore the spatial variation in source-specific ecol. risks and identify critical sources. Here, we focused on 22 PPCPs found in the effluent from wastewater treatment plants and surface water in Tianjin, and source-specific risk was quant. apportioned combining pos. matrix factorization with ecol. risk assessment. Results showed that rural areas exhibited a more severe contamination level than urban areas. Medical wastewater (30.1%) accounted for the highest proportion, while domestic sewage posed the greatest threat to aquatic ecosystems. The incidence of potential risks (RQ > 0.01) caused by domestic sewage in urban areas (88.9%) was higher than that in rural areas (75.9%). However, PPCP risks caused by farmland drainage, aquaculture, and livestock discharge were mainly distributed in rural areas. The critical source identified in the entire region was domestic sewage (weight, 0.36), and its weight (0.51) in urban areas was greater than that in rural areas (0.32). The impact of aquaculture (weight, 0.16) in rural areas was noteworthy. These findings may contribute to developing environmental management strategies in key areas to help alleviate PPCP contamination worldwide.

The abuse of antibiotics would seriously affect human health and has become of worldwide critical concern, thus it is urgent to develop an environmentally friendly and nontoxic fluorescent probe for antibiotics sensing. In this work, a lead-free Cs₂ZnCl₄ perovskite nanocrystals (PNCs) probe was fabricated for sensing norfloxacin (NOR) employing a modified ligand-assisted reprecipitation method. The prepared Cs₂ZnCl₄ PNCs probe had strong blue emission around 440 nm, and the characteristics of PNCs were systematically characterized by X-ray photoelec. spectroscopy (XPS), Fourier transforms IR spectroscopy (FTIR), transmission electron microscope (TEM) and powder X-ray diffraction (XRD). The results revealed that the fluorescence intensity of the Cs₂ZnCl₄ PNCs was significantly enhanced after the introduction of norfloxacin. The Cs₂ZnCl₄ PNCs can be used as a fluorescent probe to selectively and sensitively detect norfloxacin in the concentration range from 0.2 to 50.0 μM, with a correlation coefficient (R²) of 0.9954 and the limit of detection (LOD, 3σ) of 0.1499 μM.

The release of antibiotics from WWTPs into the environment has raised increasing concern worldwide. The monitoring of antibiotics in WWTPs throughout a region is crucial for emerging pollutant management. A large-scale survey of the occurrence, distribution, and ecol. risk of seven antibiotics in 51 WWTPs was conducted in Shaanxi Province, China. Norfloxacin and ofloxacin had the highest detection concentrations of 474.2 and 656.18 ng L-1, resp. Antibiotic residues in effluents were decreased by 5.88-94.16% after different treatment processes. In particular, A2O or mixed processes performed well in removing target antibiotic compounds simultaneously. The ecol. risk posed by antibiotic compounds detected in effluents was calculated using the risk quotient (RQ). Norfloxacin, ofloxacin, tetracycline, and roxithromycin posed different levels of potential ecotoxicol. risk (RQ = 0.02-7.59). Based on the sum of the RQ values of individual antibiotic compounds, each investigated WWTP showed potential ecol. risk. WWTPs with high risk levels were mainly found in the central region, while those in the southern region exhibited low risk levels, and those in the northern region showed risk levels between medium and high. This comprehensive investigation provides promising results to support the safe use and control of antibiotics in the study area.

Mechanistic insight into adsorptive removal of ionic NOR and nonionic DEP organic contaminates by clay-biochar composites was written by Jing, Fanqi;Guan, Junjie;Tang, Wei;Chen, Jiawei. And the article was included in Environmental Pollution (Oxford, United Kingdom) in 2022.Computed Properties of C16H18FN3O3 The following contents are mentioned in the article:

The synthesis of clay-biochar composite has been recognized as an effective way to enhance the removal of pollutants. The interaction between clay mineral and biomass during thermal pyrolysis and the sorption capacity for ionic/nonionic organic containments have not been elaborated. In this study, two types of biochar were obtained from pyrolytic carbonization of the cellulosic-rich corn straw (C) and lignin-rich pine wood (P) at 500 or 700°C. Typical clay minerals kaolinite and montmorillonite were selected to prepare clay-biochar composite. The results showed that the addition of clay mineral could strengthen dehydration reaction of corn straw biomass and reinforce its carbon structure. Montmorillonite-biochar composite owned more C=C functional groups and porous structure than kaolinite-biochar composite. The addition of clay minerals could promote electrostatic attraction of ionic formed norfloxacin (NOR) on clay-pine wood biochar. However, the sorption capacity of nonionic di-Et phthalate (DEP) adsorption on clay-corn straw biochar decreased, owing to that clay increased the compactness of the biochar carbon structure, thus inhabited hydrophobic partition of nonionic organic compounds on disordered carbon fraction. The results from this study provide insights into the suitable contaminated site remediation by clay-biochar composite.

A magnetic carbon material Co@C-600 was fabricated by the in situ thermal conversion of a precursor metal organic frameworks (CUST-563) with structure for peroxymonosulfate (PMS) activation. The composition of the material changes regularly by carbonizing the precursor at different temperatures The Cobalt-based carbon materials with well dispersibility were obtained by carbonizing MOF, which avoided aggregation and exposed more active sites. The reaction parameters (catalyst content, PMS dosage, temperature, pH value, etc.) in the oxytetracycline (OTC) degradation process had been investigated. The degradation rate of OTC (20 mg/L) in 15 min reached more than 89%. According to the ESR (EPR) test results, the degradation process was carried out by the synergistic effect of two degradation mechanisms: free radicals (SO₄^·-,·OH) and non-radicals (¹O₂) process, and Co⁰ acts as the initiator of the free radical reaction. It proved that the synthesized efficient nanocarbon-based Co@C-600 was equipped with highly stability and reusability after 10 cycles experiments This work studied the difference in the crystal at composition after calcining crystal at various temperatures and the mechanism of activation of PMS, which provided a design idea about the preparation of high-efficiency catalytic materials.

Multidrug-resistant and potentially pathogenic Enterobacteriaceae found in a tertiary hospital sewage in southeastern Brazil was written by Nakamura-Silva, Rafael;Dias, Leila Lucia;Sousa, Ricardo Coelho;Fujimoto, Rodrigo Yudi;Pitondo-Silva, Andre. And the article was included in Environmental Monitoring and Assessment in 2022.Category: piperazines The following contents are mentioned in the article:

Hospital sewage is considered an environment with the potential to favor the spread and increase of multidrug-resistant bacteria (MDR). The increase in antimicrobial resistance is one of the greatest global threats today. Therefore, this study aimed to evaluate the profile of antimicrobial susceptibility and virulence factors in Enterobacteriaceae isolated from the sewage of a tertiary hospital located in southeastern Brazil. For bacterial isolation, membrane filtering, serial dilution, and spread-plate techniques were used. The bacterial isolates were identified using the MALDI-TOF (matrix-assisted laser desorption ionization-time of flight) technique. Antimicrobial susceptibility profile was performed by disk-diffusion test. Virulence genes were screened by Polymerase Chain Reaction (PCR) and the hypermucoviscosity phenotype by string test. In total, 13 enterobacteria distributed in three species were identified (Klebsiella pneumoniae, Escherichia coli, and Citrobacter freundii) and 76.9% (n = 10) were classified as MDR. Two K. pneumoniae demonstrated the hypermucoviscosity phenotype. The virulence genes ycfM and entB were detected in all K. pneumoniae isolates (other genes found were fimH, mrkD, and kfu). The results indicated that the sewage from the analyzed hospital receives MDR bacteria and has the potential to contaminate and spread through the environment.
