“…The performance of SPE-GC-FID was compared to that of other related extraction techniques for the analysis of PAHs in terms of sample volume, solvent volume, LOD, linear range, precision, and extraction time (Table 2). 30,36–42 The results show that the precision and linear range of the proposed method are better or comparable with other methods. Also, the SPE-GC-FID method has lower LOD than MSPE/GC-FID (MGO@HMDI@β-CD), 36 MSPE/GC-FID (Fe 3 O 4 @ CNT@β-CD), 37 MSPE/GC-FID (G/Fe 3 O 4 @PT), 38 SPE-HPLC-UV (Graphene quantum dots-eggshell), 39 SPE-HPLC-FLD (Natural cotton fibers), 40 MSPE/HPLC-UV (MIL-101 (γ-Fe 2 O 3 )/MWCNT), 41 and comparable with SPME/GC-FID (Ppy/MnO 2 -fGr/[AVIm]NTf 2 ), 30 and MSPE/GC-MS/MS (MNPs@PAMAM-G2.0@GO).…”

“…The lowest detection limit in this method was 0.0015 μg/L for PAEs and 0.0003 μg/L for PAHs. Most studies have reported minimum limits of detection (LODs) to be greater than 0.005 g/L for PAEs [ 37 , 38 , 39 ] and 0.2 μg/L for PAHs [ 40 , 41 , 42 ], and the linear range of the proposed method is wider than that of other methods for the detection of PAEs and PAHs. The advantages of this work are (1) the detection of human placental tissue, (2) sophisticated detection instrumentation and inexpensive extraction reagents, and (3) combined extraction and detection of PAHs and PAEs in large quantities.…”

In this study, we evaluated the extraction effect of three different extractants, namely hexane + ether (v/v = 3:1), acetonitrile and ethyl acetate, on polycyclic aromatic hydrocarbons (PAHs) and phthalic acid esters (PAEs) in placenta detected and analysed by triple quadrupole gas chromatography–mass spectrometry (GC-MS/MS). The results showed that n-hexane + ether (v/v = 3:1) had the highest extraction efficiency. Under the optimal conditions, the limits of detection (LOD) for the 10 PAHs were 0.003–0.0167 μg/L with relative standard deviations (RSD) of 1.4–5.48% and detection rates of 68.19–107.05%, and the correlation coefficients were (R2, 0.9982–0.9999). The LODs for the nine PAEs were 0.0015–3.5714 μg/L and the correlation coefficients were (R2, 0.9982–0.9999). The limits of detection (S/N = 3) for the nine PAHs were 0.0015–0.5714 μg/L with relative standard deviations (RSD) of 3.15–8.37%, and the detection rates were 80.45–112.59% with correlations of (R2, 0.9972–0.9998). The method was applied to the analysis of PAHs and phthalates in placenta samples from pregnant women. The method’s accuracy and applicability were demonstrated. In comparison with other methods for the detection of PAEs and PAHs, the method proposed in this paper has a wider linear range, lower minimum detection limit and comparable recovery with good correlation. This paper is dedicated to providing another method for improving the performance of extracting solid tissues.

“…MPC has the characteristics of superparamagnetism and large pore volume and it retains features of the MOF even after calcination. 22 Fe-containing MILs are a class of common MOFs which have strong adsorption properties and abundant active metal sites, 23 and the ordered arrangement of metal ions in MOFs can avoid the agglomeration of magnetic particles and increase the dispersion property effectively. 24 Besides MPC calcined from various MOFs, multi-walled carbon nanotubes (MWCNTs), graphene oxide (GO) and their composite with other nanomaterials are some of the extensively used carbon materials in the extraction field, as they possess large specific surface area, abundant π-delocalized electrons and good thermal stability.…”
