Fe3O4-SiO2-MIL-53 (Fe) nanocomposite fabricated using the solvothermal technique was characterized using a field emission scanning electron microscope and X-ray diffraction. The extraction efficiency of the method was improved by optimizing the experimental factors. After optimization, the linearity range for Cd (II) was 4.3–500 µgL-1. The limits of detection and quantification were 1.3 and 4.3 µgL-1, respectively. The presented magnetic dispersion-micro solid phase extraction method was applied to Cd (II) analysis in food and some environmental samples. © 2023 Elsevier Ltden10.1016/j.foodchem.2023.136855info:eu-repo/semantics/closedAccessCadmiumFood samplesMetal organic frameworksPreconcentrationWater samplesAbsorption spectroscopyAtomic absorption spectrometryCadmium compoundsChemical contaminationDispersionsExtractionNanocompositesOrganometallicsPhase separationScanning electron microscopySilicaSynthesis (chemical)Trace elements'spice'Dispersive micro solid-phase extractionsFood samplesMagnetic metalsMetalorganic frameworks (MOFs)Microsolidphase extractionPre-concentrationSynthesisedTrace levelWater samplesMagnetitecadmiumironmagnetitemetal organic frameworknanocompositenanomaterialcadmiumnanocompositesilicon dioxideArticleatomic absorption spectrometryfield emissionlimit of detectionpHsolid phase microextractionX ray diffractionchemistrymagnetismproceduressolid phase extractionCadmiumMagnetic PhenomenaNanocompositesSilicon DioxideSolid Phase ExtractionArticle4292-s2.0-8516539230237478612Q1
