“…The developed sorbent exhibited good affinity towards the target analytes. Other examples of novel SPE sorbents that have been implemented for the extraction and preconcentration of PAHs from environmental samples include a cyclodextrin-silica microporous composite [190,191], aminopropyl imidazole-modified silica gel [192], tetraazacalix [2]arene [2]triazine [193], titanium oxide nanotubes [194] and a titanate nanotube array modified by cetyltrimethylammonium bromide [195].…”

Polycyclic aromatic hydrocarbons (PAHs) comprise a group of chemical compounds consisting of two or more fused benzene rings. PAHs exhibit hydrophobicity and low water solubility, while some of their members are toxic substances resistant to degradation. Due to their low levels in environmental matrices, a preconcentration step is usually required for their determination. Nowadays, there is a wide variety of sample preparation techniques, including micro-extraction techniques (e.g., solid-phase microextraction and liquid phase microextraction) and miniaturized extraction techniques (e.g., dispersive solid-phase extraction, magnetic solid-phase extraction, stir bar sorptive extraction, fabric phase sorptive extraction etc.). Compared to the conventional sample preparation techniques, these novel techniques show some benefits, including reduced organic solvent consumption, while they are time and cost efficient. A plethora of adsorbents, such as metal-organic frameworks, carbon-based materials and molecularly imprinted polymers, have been successfully coupled with a wide variety of extraction techniques. This review focuses on the recent advances in the extraction techniques of PAHs from environmental matrices, utilizing novel sample preparation approaches and adsorbents.

A sequential flow-based analysis system with on-line solid-phase extraction (SPE) columns coupled to microwave plasma atomic emission spectrometry (MP-AES) was developed for strontium and nickel determination. Crown ether chromatographic resin and dimethylglyoxime polymethacrylate resin were used for strontium and nickel retention under acidic and basic conditions, respectively; eluted with a nitric acid solution in both cases followed by MP-AES detection. The calculated detection limits were 0.25 μg L -1 for strontium and 3.56 μg L -1 for nickel.

“…[6][7][8][9][10] Due to their trace amounts together with the complexity of the matrices, a sample preparation method is generally required before instrumental analysis. Solid-phase extraction (SPE) is one of the established and popular methods for sample enrichment due to its high extraction efficiency.…”

A novel magnetic absorbent based on Fe3O4 hollow nanospheres was developed for polycyclic aromatic hydrocarbons (PAHs) extraction. Fe3O4 hollow nanospheres were prepared by a one-pot facile solvothermal method and its structural properties were characterized by scanning electron microscope (SEM) and analyzer transmission electron microscopy (TEM). It was the first time to use hollow nanospheres which possess high special surface area for magnetic solid-phase extraction (MSPE). The extraction condition of Fe3O4 hollow nanospheres and its performance for PAHs was systematically investigated. Besides, its extraction performance also compared with bare Fe3O4 nanoparticles. The results indicated the structure with hollow and spherical Fe3O4 perform better enrichment ability than that with solid and amorphous ones. The developed MSPE coupled with HPLC method shows good linearity (0.1 -5 ng/mL) and low detection limits (2.5 -10 pg/mL) for six PAHs. It also has been executed for the analysis of environmental samples, with recoveries in the range of 84.6 -97.8%.
