“…We concluded that the excellent enrichment ability of Fe 3 O 4 /PDA to PAHs resulted from the PDA coat. In the following experiment 20 mg of Fe 3 O 4 /PDA was employed, which was fairly lower than the amount of commercial or previously reported nanomaterial SPE adsorbents used to enrich PAHs [5,6,13,14,17,18,[26][27][28].…”

“…Nowadays, magnetic solid-phase extraction (MSPE), a novel SPE method, has been developed based on the use of magnetic nanoparticles since its high extraction efficiency and rapid extraction kinetics [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20]. The magnetic adsorbents are usually devised on the basis of Fe 3 O 4 nanoparticles.…”

“…The magnetic adsorbents are usually devised on the basis of Fe 3 O 4 nanoparticles. Due to the highly hydrophilic property of Fe 3 O 4 , a layer of hydrophobic coat or adlayer such as hemimicelles/admicelles of ionic surfactant or alkyl carboxylates groups [2][3][4][5][6], phenyl or C 18 groups [7][8][9][10][11][12][13], carbon [14][15][16], or polymers [17][18][19][20], must be immobilized on the surface of Fe 3 O 4 MNPs, which involves toxic reagents or high temperature, and multiple, complicated procedures. With regard to MSPE method established with mixed hemimicelle modified magnetic nanoparticles, the extraction efficiency is strongly dependent on certain extraction condition and the adsorbed ionic surfactant is coeluted with targets, which interferes with determination of analytes.…”

a b s t r a c tCore/shell structured magnetic Fe 3 O 4 /polydopamine (Fe 3 O 4 /PDA) nanoparticles have been successfully synthesized and developed as a magnetic solid-phase extraction (SPE) adsorbent in dispersion mode for the determination of trace polycyclic aromatic hydrocarbons (PAHs) in environmental samples. The Fe 3 O 4 /PDA synthetic procedure is simple and involves no organic solvents. Only 20 mg of Fe 3 O 4 /PDA adsorbents are required to extract PAHs from 500 mL water samples. The adsorption attains equilibrium rapidly and analysts are eluted with acetonitrile readily. The extraction efficiency is not influenced by salt concentrations up to 300 mM and pH values over the range 4-11. Under optimized conditions, the detection limits of PAHs are in the range of 0.5-1.9 ng L −1 . The accuracy of the method is evaluated by the recoveries of PAHs from environmental samples. Good recoveries (76.4-107%) with low relative standard deviations from 1.0% to 9.7% are achieved. Comparison study shows that the recoveries of target PAHs are low when they are extracted using traditional SPE method even with the addition of methanol or tetrabutylammonium bromide surfactants in water samples, suggesting great application potential of magnetic SPE method to preconcentrate highly hydrophobic contaminants (such as PAHs) from large volume of water samples. This new SPE method provides several advantages, such as simplicity, low environmental impact, high extraction efficiency, high breakthrough volumes, convenient extraction procedure, and short analysis time.

A B S T R A C TSample preparation is a crucial bottleneck in the whole analytical process. Solid-phase sorbents (SPSs) have aroused increasing interest in research on sample preparation, as they have key roles in obtaining high clean-up and enrichment efficiency in the analysis of trace targets present in complex matrices. The objective of this review is to provide a broad overview of the recent advances and applications of SPSs in sample preparation prior to chromatographic analysis, during the period 2008-13. We include SPSs, such as molecularly-imprinted polymers, carbon nanomaterials, metallic nanoparticles and metal organic frameworks, focusing on solid-phase extraction, solid-phase microextraction, matrix solid-phase dispersion and stir-bar sorptive extraction of typical pollutants in environmental, biological, food and pharmaceutical samples. We propose remaining challenges and future perspectives to improve development of new SPSs and to apply them further.

“…Among these, SPE is the most commonly used technique to preconcentrate PAHs from environmental samples as this procedure requires only a small amount of organic solvents and the adsorbent can be recovered satisfactorily afterwards. However, this method is time and labour intensive especially when it involves a large volume of sample 13 .…”
