“…First, ARA‐IIs compounds’ solubility in aqueous may be decreased by salting‐out effect, which would be beneficial to the MSPE extraction. Secondly, the presence of NaCl in aqueous can increase the viscosity of the sample solution, which would influence the dispersion of the MNPs . In our experiment, with the increasing NaCl in sample solution, the MNPs tended to float over the aqueous; thus, the interaction between MNPs and target analytes was reduced, resulting in reduced extraction efficiency.…”

Biocompatible magnetic nanoparticles that featured divinylbenzene and sulfonate functionalities were used for the magnetic solid-phase extraction of five angiotensin II receptor antagonists from human urine and plasma samples based on a reversed-phase and cationexchange mixed-mode mechanism. Under the optimized extraction conditions, coupled to high-performance liquid chromatography with fluorescence detection, this proposed method was found to be accurate and precise with relative standard deviations of less than 11.7%, and a good recovery of 80.1-119.5% for both samples. The linear ranges were 0.2-2000 and 0.2-2500 ng/mL along with correlation coefficients above 0.9923 and 0.9928 for urine and plasma samples, respectively. Limits of detection were 0.01-5.74 and 0.01-1.31 ng/mL, respectively. The proposed magnetic solid-phase extraction based on the magnetic nanoparticles functionalized with divinylbenzene and sulfonate was a reliable and convenient sample pretreatment method and had the potential for isolating and enriching the angiotensin II receptor antagonists in biological samples.

“…For instance, the determination of polycyclic aromatic hydrocarbons (PAHs) in water samples by MSPE and GC-MS has been described using three types of MNPs coated with silica, which was functionalized with C 18 [15], an IL [16] and divinylbenzene together with sulfonate groups (DVB-SO 3 Na) [17]. Although other types of MNPs have been described for PAH determination using LC and different detectors, these examples have been chosen because the use of GC-MS in the three methods selected allows the differences in their features to be mainly ascribed to the treatment step.…”

“…The sample preparation methods involving clean-up and enrichment steps are often required before the chromatographic analysis of PAHs at subtrace levels in environmental samples. The detection of PAHs in environmental water sources usually involves the use of solid-phase extraction [4], stir bar sorptive extraction [5], dispersive liquid-liquid microextraction [6], and solid phase microextraction (SPME) coupled to gas chromatography (GC) or high-performance liquid chromatography (HPLC) [7,8]. These extraction techniques have advantages such as speed, low cost, high enrichment factor, and high recovery.…”

Ionic liquid (IL) containing amino and vinyl terminated imidazolium cation and bis[(trifluoromethyl)sulfonyl] imide anion-functionalized graphene oxide (GO) coating material was prepared and coated on a stainless steel wire by a sol-gel technique for headspace-solid phase microextraction (HS-SPME). Its extraction performance was checked by HS-SPME of polycyclic aromatic hydrocarbons (PAHs) coupled to gas chromatography with mass spectrometry (GC-MS). The extraction capability of the IL-functionalized GO-coated fiber was comparable with that of the commercial fibers of polydimethylsiloxane (PDMS) and polydimethylsiloxane/carboxen/divinylbenzene (PDMS/CAR/DVB). Under the optimized conditions, such as extraction temperature, extraction time, and salting-out, the proposed HS-SPME-GC-MS method presented a wide working range from 0.003 to 40 µ g L −1 with a correlation coefficient higher than 0.996, low detection limits from 1 to 5 ng L −1 , and good precision less than 7%. The fiber-to-fiber repeatability was in the range of 0.2%-6.9%. The recoveries for 8 PAHs using the novel and commercial fibers in tap and seawater samples were obtained very close to each other and were in the range of 75.4% to 116.0%.
