How Morphological Structure and Amino-Functional Group of Adsorbents Affect the Adsorption Properties for Phenolic Acids

Published: Jan. 1, 2025

In the process of pharmacokinetic and pharmacological research new phenolic acids in vivo, a good strategy for their accurate determination is to design an effective adsorbent. The key point excellent adsorbent choice carrier structure modification functional groups. However, there are few studies focusing on how physical morphology group affect adsorption properties. this work, nine adsorbents were designed synthesized by combining extraction advantages magnetic nanomaterials, morphological characteristics dendritic mesoporous structures, capacity various types amino-silanes. Gallic acid, chlorogenic caffeic rosmarinic acid used as probe molecules acids. Effects properties, amino-silanes surface carrier, differences different all systematically investigated. Research results well confirmed that produced significantly compounds, poly-condensation reaction during post-modification seriously affected physicochemical properties Therefore, implementation work can provide data support theoretical basis design, modification, mechanisms materials, especially

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, Journal Year: 2025, Volume and Issue: 48(3)

Published: March 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.
