“…Then, the proposed method was compared with other analytical procedures reported for PFCs analysis (Table ). Obviously, our method exhibited remarkable advantages in extraction time, recoveries and LODs in PFCs analysis, in comparison with traditional extraction methods such as LLE , SPME , and SPE . The reason was probably due to superparamagnetic property and huge‐specific surface area of magnetic nanoparticles, by which fast, efficient magnetic separation, and strong adsorption capacity for PFCs could be achieved.…”

“…Thereby, sample preconcentration becomes very necessary before chromatographic analysis. Till now, multiple extraction techniques have been developed, such as LLE , LPME , solvent extraction , and SPE . SPE is particularly preferable due to high enrichment efficiency, short‐extraction time, low organic solvent consumption, and convenient for operation.…”

In this work, a novel extraction and enrichment technique based on hexadecyldimethyl amine functionalized magnetic nanoparticles has been successfully developed for the preconcentration and ultrasensitive detection of perfluorinated compounds in environmental water samples with high-performance liquid chromatography coupled with tandem triple quadrupole mass spectrometry. As a novel surfactant, hexadecyldimethyl amine functionalized on magnetic nanoparticles was realized through one-step facile and robust quaterization reaction, greatly superior to previous multiple-step and unstable modification. The functional nanoparticles of homogeneous nanospheres and excellent magnetic properties were characterized with scanning electron microscopy, X-ray diffraction patterns, Fourier transform infrared spectroscopy, and vibrating sample magnetometry. Dual mechanisms of both hydrophobic and electrostatic interactions were simultaneously introduced for anionic perfluorinated compounds effective enrichment. Under optimized extraction conditions, satisfactory precision and accuracy for anionic perfluorinated compounds analysis were achieved with good linear ranging from 0.5 to 20 ng/L, as well as fascinating sensitivity with low limits of detection up to 3.0 × 10(-2) -5.0 × 10(-2) ng/L. High preconcentration efficiency and extraction recoveries ranged from 81.04-103.2% with relative standard deviations (n = 5) less than 10% have also been realized. Thereby, our proposed method is convenient and efficient for enrichment, exhibiting good application prospect in future environmental perfluorinated compounds analysis.

“…For instance, anionic perfluorinated compounds have been extracted from water samples using CTAB-MNPs [30] and hexadecyldimethyl amine-MNPs [31], obtaining recoveries in the range of 84.5 -106.4% and 81.0 -103.2%, respectively, which were better than those obtained using liquid-liquid extraction (60 -70%) [32] or conventional SPE (57 -103%) [33].…”

“…However, these sampling techniques share the low extraction selectivity for PFCs. Recently, Bailey et al used fluorous solvents such as perfluorobutylmethyl ether, trifluoroethanol and perfluorohexane partitioning PFCs from food matrices, which was a successful application of fluorous affinity in the extraction of PFCs with high selectivity. However, the extracted liquor needed to be stored at –80°C overnight to reform the triphasic system.…”

In this work, the interior-walls decyl-perfluorinated functionalized magnetic mesoporous microspheres (F(17)-Fe(3)O(4)@mSiO(2)) were synthesized for the first time, and applied as adsorbents to extract and concentrate perfluorinated compounds (PFCs) from water samples. The fluorous functionalized interior pore-walls contributed to the high-selective preconcentration of PFCs due to fluorous affinity; and abundant silanol groups on the exterior surface of microspheres contributed to the good dispersibility in water sample. Four kinds of PFCs were selected as model analytes, including perfluorooctanoic acid, perfluorononanoic acid, perfluorododecanoic acid, and perfluorooctane sulphonate. In addition, UHPLC-ESI/MS/MS was introduced to the fast and sensitive detection of the analytes after sample pretreatment. Important parameters of the extraction procedure were optimized, including salinity, eluting solvent, the amount of F(17)-Fe(3)O(4)@mSiO(2) microspheres, and extraction time. The optimized procedure took only 10 min to extract analytes with high recoveries and merely 800-μL acetonitrile to elute analytes from the magnetic adsorbents. Validation experiments showed good linearity (0.994-0.998), precision (2.6-7.6%), high recovery (93.4-105.7%) of the proposed method, and the limits of detection were from 0.008 to 0.125 μg/L. The F(17)-Fe(3)O(4)@mSiO(2) magnetic microspheres have the advantages of great dispersibility in aqueous solution, high specificity of extraction, large surface area, and efficient separation ability. The results showed that the proposed method based on F(17)-Fe(3)O(4)@mSiO(2) microspheres is a simple, fast, and sensitive tool for the analysis of PFCs in water sample.
