“…Therefore, it 39 and chitosan-coated C18-functionalized magnetite nanoparticle, 40 had been used for the MSPE of some PAEs in water and beverage samples with excellent results. Compared with the reported MSPE methods, less time was needed for the current process, which indicated a high extraction efficiency of the LC-based magnetic nanocomposite for the PAEs.…”

In this paper, a layered-carbon-Fe 3 O 4 (LC-Fe 3 O 4 ) hybrid material was synthesized through a facile one-pot solvothermal method and used as the adsorbent for the preconcentration of some phthalate esters (dimethyl phthalate, diethyl phthalate, diallyl phthalate, diisobutyl phthalate and benzyl butyl phthalate) in water samples. The effects of the adsorbent dosage, extraction time, the solution pH and salinity on the adsorption of the phthalate esters (PAEs) were investigated. The magnetic nanocomposite adsorbent could remove and enrich the PAEs from water samples efficiently. After the adsorption, the analytes were desorbed and then determined by high performance liquid chromatography-ultraviolet detection. Under the optimum conditions, the enrichment factors of the method for the analytes were in the range from 161 to 180. A linear response with peak area as the quantification signal was observed in the concentration range from 0.5 to 100 ng mL . The method was suitable for the determination of trace phthalate esters in environmental water samples.

“…CNTs in sample preparation have been reviewed in detail by Zhang et al [32]. Using magnetic MWCNTs as SPE sorbents can avoid tedious steps, such as centrifugation and filtration [135][136][137][138]. And self-assembled poly(diallyldimethylammonium chloride) (PDDA)-functionalized MWCNTs were used as anion-exchange sorbents for extraction of acidic degradation products of nerve agents [139].…”

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.

“…Up to now, various pretreatment techniques have been carried out to extract PEs from different samples, 4 such as ionic liquid cold-induced aggregation dispersive liquidliquid microextraction (IL-CIA-DLLME), 5 dispersive liquid-liquid microextraction (DLLME), 6 graphenebased magnetic nanocomposite, 7 and magnetic carbon nanotubes (CNTs). 8 Recently, an air-assisted liquid-liquid microextraction method (AALLME) as a new version of DLLME was developed for extraction and preconcentration of some compounds in aqueous samples. [9][10][11] In this method, a solvent-coated bubble is used to contact organic and aqueous phases.…”

In this study, a highly sensitive and reliable microextraction method, known as in tube ultrasonic and air assisted liquid-liquid microextraction (IT-UAA-LLME), was developed for the preconcentration of some phthalate esters, such as dimethyl phthalate, diethyl phthalate (DEP), di-butyl-phthalate (DBP), bis(2-ethylhexyl) phthalate (BEHP), butyl benzyl phthalate (BBP), and di n-octyl-phthalate (DNOP), prior to their determination using gas chromatography-mass spectrometry (GC-MS). In this technique, the extraction solvent was dispersed into the aqueous sample solution using an ultrasonic bath. The effects of solvent type, aeration time and salt concentration were investigated. After extraction, an organic solvent was injected into the GC-MS instrument for quantification. Under optimum conditions, the enrichment factors ranged from 100 to 330. The calibration curves showed good linearity (r 2 > 0.99) and limit of detections were obtained in the range of 0.1-2.1 ng mL -1 in the working concentration ranges. The method was successfully applied for determination of six phthalate esters in real samples with complex matrices with relative standard deviation less than 8%, recovery 88-112% and thus, satisfactory results were obtained.
