“…The GO was suspended in a solution and then reacted with the polydopamine-SS wire forming the GOF-SS wire SBSE bar [ 52 ]. Another way to produce SBSE bars is by magnetic fixation of the sorbent to the stirring bar [ 25 ]. This bar type is used in a sample preparation technique called stir bar sorptive-dispersive microextraction (SBSDμE).…”

“…As the name suggests, this technique introduces the coated magnetic bar into the sample solution, and under fast stirring the sorbent is dispersed in the solution. After the end of the stirring, the magnetic bar attracts the sorbent forming against the coated bar, which can be removed by plastic forceps [ 25 ]. A recent application of this technique using graphene-based materials for water analysis was the use of an SBSDμE device composed of a neodymium stir bar coated by graphene (G) fixed on Fe 3 O 4 particles’ sorbent (G-Fe 3 O 4 ) in the determination of seven pesticides in water [ 25 ].…”

“…The diversity of potential functionalizations of graphene-based materials allows for a wide range of applications in separation science. These applications include the use of techniques such as stir bar sorptive extraction (SBSE) [ 25 , 26 ], dispersive solid phase extraction (d-SPME) [ 27 , 28 ], fiber solid phase microextraction (Fiber-SPME) [ 29 , 30 ], in-tube solid-phase microextraction (IT-SPME), and others [ 2 , 24 ] in sample preparation methods. Additionally, graphene-based materials have been explored as packing materials for analytical columns in LC, including using graphene oxide (GO) fixed to silica particles functionalized with C18, graphene (G) fixed to silica particles modified with gold nanoparticles, and reduced graphene oxide (rGO) coated with cellulose fixed to silica particles [ 31 , 32 , 33 , 34 ].…”

This review provides an overview of recent advancements in applying graphene-based materials as sorbents for liquid chromatography (LC) analysis. Graphene-based materials are promising for analytical chemistry, including applications as sorbents in liquid chromatography. These sorbents can be functionalized to produce unique extraction or stationary phases. Additionally, graphene-based sorbents can be supported in various materials and have consequently been applied to produce various devices for sample preparation. Graphene-based sorbents are employed in diverse applications, including food and environmental LC analysis. This review summarizes the application of graphene-based materials in food and environmental water analysis in the last five years (2019 to 2023). Offline and online sample preparation methods, such as dispersive solid phase microextraction, stir bar sorptive extraction, pipette tip solid phase extraction, in-tube solid-phase microextraction, and others, are reviewed. The review also summarizes the application of the columns produced with graphene-based materials in separating food and water components and contaminants. Graphene-based materials have been reported as stationary phases for LC columns. Graphene-based stationary phases have been reported in packed, monolithic, and open tubular columns and have been used in LC and capillary electrochromatography modes.

Extensive use of organophosphorus pesticides in agriculture leads to adverse effects to the environment and human health. Sample preparation is compulsory to enrich target analytes prior to detection as they often exist at trace levels and this step is critical as it determines the concentration of pollutants present in samples. The selection of a suitable extraction method is of great importance. The analytical performance of the extraction methods is influenced by the selection of sorbents as sorbents play a vital role in the sensitivity and selectivity of an analytical method. To date, numerous sorbent materials have been developed to cater to the needs of selective and sensitive pesticides’ detection. Comprehensive details pertaining to extraction methods, developed sorbents, and analytical performance are provided. This review intended to provide a general overview on different extraction techniques and sorbents that have been developed in the last 10 years for organophosphorus pesticides’ determinations in food and water samples.

“…There are many analytical methods for extraction of PAHs from water resources including dispersive liquid-liquid microextraction (20), pressurized liquid extraction (21), solid-phase extraction (22), solid-phase microextraction (23), simultaneous distillation extraction (24), headspace solid-phase microextraction (25), stir bar sorptive extraction (26), and so on, which are often used manually. Solid phase extraction (SPE) is one of the most common forms of sample preparation used for the extraction, changing of solvents, clean-up, concentration, and matrix simplification of PAHs.…”

Considering the adverse effects of polycyclic aromatic hydrocarbons (PAHs) on human health and the complexity of their detection in water resources, this study was developed to assess the performance of a new automated device for the identification of PAHs in water based on the solid-phase extraction and to simulate the cancer risk of 16 priority PAHs by Monte Carlo technique. All operational modes of extraction were automatically performed using the proprietary software program. Three spiked aliquots of PAHs including 100, 500, and 1000 ng/L were used to evaluate the performance of the automated-solid phase extraction (SPE) apparatus. The time of extraction in the automatic-SPE apparatus was 50±4 minutes for simultaneous extraction of 4 water samples, which was four times faster than that of manual-SPE apparatus. The mean recoveries of PAHs were 89.22±4.94, 91.70±4.45, and 94.61±6.28% in spiked samples, with a mean of 91.84±5.22%. Except for naphthalene, all obtained recoveries were in an acceptable range (85-115%). The results of Monte Carlo simulation showed that the cancer risk attributable to eight detected PAHs including naphthalene, fluorene, phenanthrene (Phe), benzoanthracene, chrysene, benzo(k) fluoranthene, indeno(cd)pyrene, and dibenzo(a,h)anthracene ranged from 0.05E-6 to 0.11E-6, with the cancer risk of 0.012E-6 having the highest probability (P=0.82). Additionally, this simulation showed that 99% of the probability density of cancer risk was located within the range lower than 0.05E-6. Our results showed that the novel automated-SPE apparatus could be utilized for the extraction of PAHs from water resources with a good recovery (85%-115%), high operational speed, and potential for separation of solvents from the air in the drying step. Therefore, this device can be used for the extraction of trace PAHs and similar organic compounds from water resources.
