Magnetic Solid‐Phase Extraction of Benzoic Acids in Fruit Juices Using Hydrophilic Metal‐Organic Framework MIL‐101(Cr) Coated with Magnetic Nanoparticles

Journal of Separation Science, Год журнала: 2025, Номер 48(3)

Опубликована: Март 1, 2025

ABSTRACT In this study, magnetic Fe 3 O 4 ‐coated metal‐organic framework composites, CONH 2 ‐MIL‐101(Cr)/Fe , were synthesized by depositing particles on the surface of amidated MIL‐101(Cr). The scanning electron microscope images show that MIL‐101(Cr) crystals uniformly coated particles. hysteresis curve reveals a saturated magnetization value 23.47 emu/g. water contact angle decreases from 61.00° to 12.88° after amidation and coating. solid‐phase extraction (MSPE) efficiency for benzoic acid derivatives was studied. Under optimal conditions, adsorption desorption processes can be completed within 5 min, maximum capacity protocatechuic (PCA) vanillic (VA) is 10.31 17.30 mg/g. Coupling MSPE with high‐performance liquid chromatography‐ultraviolet detection, detection limit PCA VA 0.29 0.58 ng/mL, respectively. mean recoveries in spiked samples ranged 82.85%–91.27% relative standard deviations lower than 0.33%–5.33%. This study provides inspiration fabrication novel sorbents, reliable method analysis derivatives.

Synthesis and characterization of MIL-88 A(Fe)/C composite for treatment of dairy factory’s wastewater by enhanced electro-Fenton method

Scientific Reports, Год журнала: 2025, Номер 15(1)

Опубликована: Март 12, 2025

This research focuses on addressing the environmental challenges posed by dairy wastewater problems using advanced oxidation processes (AOP). study uses a composite of MIL-88 A(Fe)/C with an electro-Fenton process to mitigate organic pollutants in wastewater. The is synthesized combining MIL88-A carbon hydrothermal process, and its morphological characterization was investigated spectroscopy microscopy methods. parameters pH, time, concentration, oxidizer concentration were optimized response surface method (RSM). In all experiments, electrode distance 3 cm current density 9 A/m2. A quadratic model fitted data. Comparison adjusted R2 predicted validated model. Kinetic studies revealed it followed pseudo-second-order behavior. optimum conditions for reducing COD pH 7.0, contact time 102.6 min, catalyst 0.5 g/L, oxidizing Na2S2O8 0.026 M. Under these conditions, removal efficiency from Isfahan Pegah Dairy factory's statistically equal 86.6% experimentally 89%. results composite, low-cost graphite, titanium electrodes competitive promising compared previous Wastewater Industries.
