Magnetic solid-phase extraction based on magnetic multi-walled carbon nanotubes for the determination of polycyclic aromatic hydrocarbons in grilled meat samples

Magnetic solid-phase extraction using carbon nanotubes as sorbents: A review

“…The synthesis is represented schematically in Figure organic compounds (such as polycyclic aromatic hydrocarbons [58] or atrazine [59])…”

“…In 2010, Morales-Cid et al [45] reported PAHs have been preconcentrated from several food samples, such as edible oils [90] and grilled meat [58], using magnetic-MWCNTs prepared by co-precipitation of iron salts and subsequent magnetite particle aggregation on the nanotube surface as the sorption material. In both cases, detection was carried out by gas chromatography mass spectrometry (GC-MS) and good LODs (0.10-0.88 and 0.035-010 ng g -1 , respectively) and acceptable inter-and intra-day precision (<9% and <13.9%) were achieved bearing Other applications of M-SPE with strategies similar to those described above have been reported for the determination of other organic compounds in environmental and food samples, including para-hydroxybenzoates [61], linear alkylbenzene sulfonates [105] (from C 10 to C 13 ) and 4-nonylphenol [106] (See Table 3 for details).…”

Magnetic Solid Phase Extraction Applied to Food Analysis

“…A variety of analytical techniques has been applied in the determination of different types of residues in food samples using the combination of MSPE with capillary electrophoresis [25][26][27], gas chromatography [45][46][47], high performance liquid chromatography/mass spectrometry (HPLC/MS) [48][49][50][51][52][53][54][55], atomic absorption spectrometry (AAS), inductively coupled plasma optical emission spectrometry (ICP-OES) [36][37][38], high performance liquid chromatography (HPLC) [48,[56][57][58][59][60][61][62][63][64], and spectrofluorimetry [65].…”

Chemometric-based determination of polycyclic aromatic hydrocarbons in aqueous samples using ultrasound-assisted emulsification microextraction combined to gas chromatography–mass spectrometry

“…They are generated during the incomplete combustion of fossil fuel, oil refinement, and industrial and municipal discharges. Also, tobacco and barbequed or smoked meat are potential matrices to find the PAHs [1,2]. PAHs have attracted attention of biochemists and analytical chemists because of their carcinogenicity, mutagenicity, toxicity and environmental persistence.…”
