Vortex‐Assisted Magnetic Solid‐Phase Extraction of Heavy Metals in Water and Food Samples Using Iron Oxide Nanoparticle‐Impregnated Carboxymethyl‐β‐Cyclodextrin

Journal of Separation Science, Journal Year: 2024, Volume and Issue: 47(20)

Published: Oct. 1, 2024

ABSTRACT The excessive accumulation of heavy metals has adverse effects on the human body. Here, magnetic iron oxide‐impregnated carboxymethyl‐β‐cyclodextrin was synthesized. synthesized material employed as a solid‐phase extracting adsorbent for specific like lead (Pb), nickel (Ni), copper (Cu), and cobalt (Co). Characterization performed by X‐ray diffraction, energy dispersive spectroscopy, scanning electron microscopy, Brunauer–Emmett–Teller, Fourier‐transform infrared spectroscopy. analytical merits, detection limits (Pb: 1.38 ng/mL, Ni: 0.5 Co: 0.14 Cu: 0.55 ng/mL) quantification 4.14 1.62 1.85 1.82 were calculated. Similarly, preconcentration enhancement factors (15) relative standard deviation 3.5, 0.92, 2.7, 1.5) also interfering study shows that method is highly selective. For validation, it applied to certified reference materials such Institute Nuclear Chemistry Technology ornamental Basma tobacco leaves trace metal double addition 63.4 environmental water with good percent recovery values (92%–99%). Real food samples used satisfactory (90%–99%) results.

ABSTRACT To further improve the dilemma facing clinical application of doxorubicin (DOX), we designed a cathepsin B sensitive DOX prodrug albumin nanoparticle (NP). evaluate pharmacokinetics NPs (C16‐GFLG‐PAB‐DOX NPs), developed and validated liquid chromatography‐tandem mass spectrometry method for same time analysis its fatty acid (C16‐GFLG‐PAB‐DOX) in rat plasma. The uses precipitated protein to extract analytes from on selectivity, linearity ( r ≥ 0.992), precision (relative standard deviation: 3.5%–9.5%), accuracy error: −2.9% 3.5%), extraction recovery (80.2% 90.4%), matrix effect (87.8% 96.6%), stability different conditions were satisfied. Therefore, pharmacokinetic behavior C16‐GFLG‐PAB‐DOX rats was investigated using this analytical approach. outcome study illustrated that are promising alleviate problems associated with applications.
