The addition of hexane may facilitate the separation of the oily fraction and the aqueous phase, but special attention should be devoted to avoid analytes losses by dissolution in the hexane, considering their nonpolar nature.…”

“…Moreda, Rodríguez-Acuña, Pérez-Camino, and Cert (2004) combined the two strategies previously presented (SPE both to extract the PAHs from the oil and also to purify the obtained extract) through the application of POO samples to silica cartridges (extraction step) and the performance of an additional SPE to remove interferences and procure cleaner chromatograms (purification step). This approach has been reproduced afterward by the teams of Rodríguez-Acuña, Pérez-Camino, Cert, and Moreda (2008a) and Taghvaee et al (2016).…”

“…The most widely used columns are based on modified C18 stationary phases, with 4.6 mm × 250 mm as typical dimensions and 5 µm particle size. Nevertheless, columns with different lengths, diameter, and particle sizes have been also employed (as can be observed in Table 2) (Alves da Silva et al, 2017Silva et al, , 2018Shi et al, 2018;Shi, Liu, Liu, & Zhang, 2015;Taghvaee et al, 2016). The optimum separation conditions usually imply a solvent gradient with ACN and water.…”

Polycyclic aromatic hydrocarbons (PAHs) are food contaminants whose presence in foodstuffs is especially alarming due to their carcinogenic character. These substances are highly lipophilic and thus, unsafe levels of these compounds have been found in edible fats and oils. Efficient methodologies to determine such molecules in lipidic matrixes are therefore essential. In this review, a detailed description of the analytical methods for the determination of PAHs in vegetable oils from the last 15 years has been provided. Particular emphasis has been placed on innovative sample treatments, which facilitate and shorten the pretreatment of the oils. Finally, results from recent investigations have been reviewed and studied in depth, in order to elucidate which PAHs are most commonly found in vegetable oils.

“…Lipid content has a great effect on the extraction recoveries for analytes, and thus it should be removed as complete as possible prior to microextraction procedures. In previous reports, many methods have been utilized to clean up lipids such as liquid-liquid extraction (Taghvaee, Piravivanak, Rezaei, & Faraji, 2016), low-temperature freezing cleanup method (Chen et al, 2009;Liu et al, 2009) and solid phase extraction (Mojtaba, Najmeh & Mahnaz, 2016). In this investigation, the milk samples were firstly stored at 4°C, then centrifuged to remove proteins, and the subsequent MET-ILM procedures had the role in purifying lipid.…”

Magnetic effervescent tablets containing ionic liquids as a non-conventional extraction and dispersive agent for determination of pyrethroids in milk

et al. 2018

Conventional magnetic effervescent tablet has many drawbacks, such as not practicable for field processing, rapid moisture absorption, and poor tablet storage characteristics. Herein, we developed a novel magnetic effervescent tablet containing ionic liquid microextraction (MET-ILM) for determination of pyrethroids in dairy milk. It contains only NaCO as an alkali source (no acidic source) in the FeO magnetic tablet; the CO-forming reaction is initiated in the acidic solution containing the analytes, and thus the prepared tablet can be stored for long time periods without deterioration. The combined action of extractant and sorbent vastly increase the extraction efficiency. The optimized procedure consisted of an effervescent tablet, 2:1 HCl:NaCO, and 60 μL [CMIM]PF as extraction solvent. The LODs for five pyrethroids were 0.024-0.075 μg kg with recoveries of 78.3-101.8%. The RSDs were <4.8% and <6.3% for intra- and inter-day precisions. Overall, the method is very feasible for use in the field.

“…The core of SPE is the adsorbent that determines the selectivity and sensitivity of the method. However, the widely used commercial SPE adsorbents, such as bonded silicas (C 8 , C 18 ), Graphene , Alumina N , and nanomaterials are often limited by their shortcomings, such as the high costs, potential health, and environmental risks and the narrow applicable ranges. Thus, developing new SPE adsorbents is of high value.…”

The coadsorption of mixed anionic-nonionic surfactants, sodium dodecylbenzenesulfonate with Triton X-100, on the surface of eggshell membrane was investigated based on adsorption isotherms to improve the solid-phase extraction performance of eggshell membrane toward organic contaminants. Results showed that even though excess Triton X-100 might inhibit the adsorption of sodium dodecylbenzenesulfonate, a low dosage of Triton X-100 can significantly improve sodium dodecylbenzenesulfonate modification and enhance the extraction efficiency of eggshell membrane from 73.7 to 100.4% because of the formation of mixed hemimicelles. The highest recovery was achieved at 2:8 (Triton X-100/sodium dodecylbenzenesulfonate mass ratios), and multiple mechanisms involving π-π interactions, hydrophobic effect, and π-π electron donor-acceptor interactions contributed to the strong extraction affinity. When mixed, the Triton X-100 and sodium dodecylbenzenesulfonate modified eggshell membrane packed cartridge coupled with high-performance liquid chromatography was applied for the simultaneous determination of trace Sudan I-IV, and low detection limits (0.16-0.26 ng/L) were achieved with satisfactory linearity (R > 0.999) in 10-10 000 μg/L. For real samples, Sudan II and III in one chilli sauce sample were found at 4.3 and 1.7 μg/kg. Sudan I-IV recoveries at three spiked levels were 87.4-102.9% with precisions <6.8%. Comparison with commonly used solid-phase extraction adsorbents and methods further reflected the superiorities of the proposed adsorbent in sensitivity, retention ability, and applicability.
