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 preparation and application of a lead-free perovskite fluorescent probe for norfloxacin would promote the application of perovskite fluorescent probes in biochem. assays.

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.

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.

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.

Peroxydisulfate (PDS) can be activated by electrochemistry, for which using atom H* as an activator is feasibly favorable in theoretical and experimental applications. Studies have shown that atomic H* can cleave the peroxide bond as a single-electron reducing agent in Na₂S₂O₈ to generate SO₄^•-, thus achieving the degradation of pollutants. Herein, Pd nanoparticles synthesized by in an in situ solution were dispersed in carbon black and then loaded on carbon felt, called Pd/C@CF, as the cathode for peroxydisulfate activation. This showed an ideal degradation effect on a small electrode (10 mm × 10 mm). Cyclic voltammetry (CV) and linear sweep voltammetry (LSV) tests were taken to verify the significant increase in the yield of the reduction of Na₂S₂O₈ by H*. The degradation experiments and free-radical scavenging experiment confirmed that the atomic H* was the dominant component triggering the activation of PDS to generate SO₄^•-. A Pd/C@CF composite electrodes have low pH dependence, high stability and recyclability, etc., which has many potential practical applications in wastewater treatment. In addition, H* can also reduce H₂O₂ to •OH by breaking the peroxide bond, so the removal of pollutants by the same amount of H₂O₂ and Na₂S₂O₈ under the same conditions is compared, and their application prospects are analyzed and compared.

The construction of a novel multifunctional adsorbent for simultaneous sensitive detection and capture of multiple antibiotic residues in the environment and food samples remains challenging. In this paper, the novel magnetic porous biochar (MPBC) derived from low-cost degreasing cotton was well-constructed and prepared via a simple solvent-free and one-step carbonization which has a large surface area, 3D porous structure, and good magnetism. The acquired MPBC was first used as multifunctional adsorbents for synchronous sorptive removal, sensitive detection, mol. sieve selection, and magnetic separation, exhibiting excellent adsorption capacity (102.2 mg g^-1) for multiple antibiotics (quinolones and sulfonamides) residue. Meanwhile, the MPBC could exclude the relatively large matrix compounds, thus eliminating matrix effects. What’s more, this method has a higher detection sensitivity, a lower detection limit (0.043-0.067μg L^-1), and higher enrichment factors (111 <EFs<133) for trace multiple antibiotics detection by high-performance liquid chromatog. (HPLC). Consequently, a fast, economical, effective, and sensitive method for analyzing of antibiotics in the environment and food samples was developed, and maybe it is an useful guide for routine detection in the food and environment inspection department. All of this indicates that MPBC is promising for simultaneous sensitive determination and efficient adsorption of multiple antibiotic residues in the environment and food samples.
