“…The development of magnetic adsorbents with highly efficient extraction capacity has become a hot research field. Up to now, various MSPE adsorbents, such as polymers [29,30], C18 nanoparticles [28], ionic liquid [31], activated carbon [32], carbon nanotubes [33] and graphene [27] have been explored.…”

A magnetic microporous carbon material was synthesized from sucrose and using a zeolite as a hard template, followed by the in situ chemical coprecipitation of Fe(II) and Fe(III) ions to impart magnetism. The resulting material was used as a sorbent for the extraction of the phthalic acid esters (PAEs) dimethyl phthalate, diethyl phthalate, diallyl phthalate and di-n-propyl phthalate. Following desorption with acetone, the PAEs were quantified by HPLC. The effects of the amount of the sorbent, extraction time, sample pH, salt addition and desorption conditions were optimized. Under the optimum conditions, the calibration plots are linear in the 0.1-50 ng mL −1 concentration range, and the limits of detection (at an S/N of 3) are at 30 pg mL −1 as demonstrated in the analysis of fruit juice samples.

A novel magnetic material Fe(3)O(4)/SiO(2)/P(MAA-co-VBC-co-DVB) was prepared via the hypercrosslinking of its precursor which was produced via precipitation polymerization of methacrylic acid (MAA), vinylbenzyl chloride (VBC), and divinylbenzene (DVB) in the presence of Fe(3)O(4)/SiO(2) submicrospheres with the surface containing abundant reactive double bonds. The resultant sorbent was characterized by scan electron microscopy, N(2) adsorption, and Fourier transform infrared spectroscopy. It was found that this material had remarkable features such as large surface area (500 m(2)/g) and pore volume (0.32 cm(3)/g), as well as desirable chemical composition (including hydrophobic and ion-exchange moieties). Taking advantages of the Fe(3)O(4)/SiO(2)/P(MAA-co-VBC-co-DVB), a magnetic SPE (MSPE) coupled with capillary electrophoresis (CE) method was developed for the determination of illegal drugs in urine samples. The extraction time could be clearly shortened up to 3 min. The recoveries of these drug compounds were in the range of 84.0-123% with relative standard deviations ranging between 1.7 and 10.5%; the limit of detection was in the range of 4.0-6.0 μg/L. The proposed method is simple, effective, and low-cost, and provides an accurate and sensitive detection platform for abused drug analysis.

“…Furthermore, temperature-response 151 and light-response polymers and polymer-coated magnetic particles [152][153][154] may be useful as an intelligent polymer device for selective sample preparation. One of the main practical obstacles to SPME implementation to date has been the lack of commercial devices with appropriate characteristics, such as biocompatibility and good inter-fiber precision, for this type of application.…”
