ABSTRACT Polycyclic aromatic hydrocarbons (PAHs) are carcinogenic compounds resulting from incomplete burning of organic materials. This work describes the successful layer‐by‐layer fabrication a novel zinc oxide nanocomposite made nanoparticles, aniline, sodium dodecyl sulfate, and modified multi‐walled carbon nanotubes on stainless steel wire by electrodeposition. The coating extraction conditions were screened, optimized, validated using factorial design central composite design, respectively. prepared nanocomposites characterized Fourier‐transform infrared spectroscopy, field‐emission scanning electron microscopy, X‐ray diffraction analysis, Brunauer‐Emmett‐Teller techniques. It featured porous structure, excellent heat stability, high capacity. also adhered well to surface. Extracting PAHs was optimized through experimental design. optimal obtained for 60 min, 30%, 30°C time, amount salt, temperature, method generally showed linear range between 0.01 1.50 µg/mL with linearity (R 2 ) 0.9902–0.9992, limits detection less than 0.003 µg/mL, limit quantification lower 0.010 relative standard deviation percent 45. Recovery values analytes in food samples varied 53.4% 110.1%. proposed employed determination some while naphthalene, anthracene, phenanthrene, benzo[a]pyrene, benz[a]anthracene detected certain samples. Overall, our research suggests as potential fiber that enables high‐capacity PAH extraction.

Quercetin‐Based Magnetic Porous Organic Polymers for Efficient Adsorption of Phenolic Pollutants

Macromolecular Chemistry and Physics, Год журнала: 2025, Номер unknown

Опубликована: Фев. 17, 2025

Abstract Phenolic wastewater poses a significant threat to public health, highlighting the urgent need for development of effective and efficient treatment methods. Porous organic polymers, renowned their high structural stability, large surface area, diverse physicochemical properties, have gained widespread application in adsorption‐based technologies. Therefore, novel adsorbent materials remains crucial area scientific research. In this study, porous polymer is synthesized using quercetin, derived from biomass, as key precursor. To facilitate separation reusability, magnetic Fe 3 O 4 @SiO₂ nano‐particle nanoparticles (MNPs) are integrated into matrix. The resulting adsorbents exhibited outstanding adsorption capacity phenolic contaminants, along with excellent recoverability reusability. Additionally, mechanism systematically investigated verified through series characterization techniques.

Novel Room‐Temperature‐Prepared Covalent Organic Framework as Adsorbent for Rapid Extraction of Aromatic Esters in Baijiu

Journal of Food Science, Год журнала: 2025, Номер 90(4)

Опубликована: Апрель 1, 2025

ABSTRACT Developing a rapid, efficient, and environmentally friendly analytical methodology for the determination of aromatic esters (AREs) in Baijiu presents significant challenge. In this study, we developed room‐temperature method to synthesize core‐shell Fe 3 O 4 @TPB‐Dha 1 h using pre‐prepared nanoparticles, enabling rapid sensitive detection AREs. The demonstrated exceptional adsorption capabilities (52.63–58.82 mg/g) with brief duration (4 min) four AREs as magnetic solid phase extraction (MSPE) adsorbent. Moreover, density functional theory (DFT) calculations revealed key mechanisms be hydrogen bonds, van der Waals forces, π–π interactions. Ultimately, enabled accurate quantification real samples, concentrations spanning from 0.17 ± 6 × 10 −4 2.40 0.03 mg/L, exhibited relative standard deviations below 6.57% ( n = 3). These findings suggest that holds promise an effective adsorbent efficient precise Baijiu.
