“…To overcome these challenges, different configurations of SPE have been adopted in sample enrichment strategies. SPE is a modern sample pre-treatment technique employed to concentrate analytes from liquid samples and to remove matrix interferents during the clean-up step, achieving exemplary recoveries and reproducible results over LLE [96,97]. SPE protocols are usually performed by the use of a small column or separation cartridge packed with an appropriate sorbent material [98,99].…”

“…Whereas in the off-line protocol, a pre-concentration step is done separately using cartridges and further eluting the adsorbed analyte with an appropriate solvent for eventual chromatographic analysis [101]. Because of its robustness and flexibility, SPE has been widely employed in different analytical procedures in pre-concentration and clean-up steps in the determination of PBDEs [96,102].…”

Environmental pollution has been a challenging phenomenon in most developing countries, due to the weak enforcement of environmental regulations. As a result, humans and animals are exposed to different environmental pollutants, which threaten their very existence. Some of the emerging pollutants of great concern are polybrominated diphenyl ethers (PBDEs) since they are categorized as probable human carcinogens and are also known to bioaccumulate in fatty tissues of animals and humans, reaching toxic levels upon continued exposure. Monitoring of these pollutants is therefore paramount as it contributes to addressing the problem of human exposure and environmental pollution. Their monitoring involves sample preparation methods followed by quantification with various detection techniques. Sample preparation methods that aim at reducing matrix interferences, enriching analytes and transfer of analytes to a desirable solvent, have evolved from conventional methods to advanced methods that facilitate the detection of these chemicals at very low concentrations. Likewise, detection techniques have advanced from chromatographic detection techniques to miniaturized systems that involve sensors. This chapter discusses PBDEs as emerging pollutants, their sources, and toxicological implications on humans, as well as advances in sample preparation methods and detection techniques in the determination of PBDEs.

“…In the analytical chemistry field, they have been used as parts of sensors [ 7 , 22 ]; in gas chromatography (GC) [ 12 , 23 ], in liquid chromatography (LC) [ 24 , 25 ] and in capillary electrochromatography [ 26 , 27 ] stationary phases; and mainly, as sorbents for analyte extraction and clean-up [ 28 , 29 , 30 ]. In fact, their use in sorbent-based extraction techniques, like other nanomaterials, has driven important advancements in the last few years, since their introduction has allowed overcoming some of the deficiencies of conventional sorbents, such as the poor extraction of polar compounds; low adsorption capacity and specificity for the analysis of trace or ultratrace analytes in complex samples; and the use of large volumes of solvents [ 31 ]. However, it is important to mention that their obtention follows complex synthetic routes in many cases, most of which cannot be developed at the industrial scale yet, making difficult their commercialization, contrary to most of conventional sorbents.…”

Covalent organic frameworks (COFs) can be classified as emerging porous crystalline polymers with extremely high porosity and surface area size, and good thermal stability. These properties have awakened the interests of many areas, opening new horizons of research and applications. In the Analytical Chemistry field, COFs have found an important application in sample preparation approaches since their inherent properties clearly match, in a good number of cases, with the ideal characteristics of any extraction or clean-up sorbent. The review article is meant to provide a detailed overview of the different COFs that have been used up to now for sample preparation (i.e., solid-phase extraction in its most relevant operational modes—conventional, dispersive, magnetic/solid-phase microextraction and stir-bar sorptive extraction); the extraction devices/formats in which they have been applied; and their performances and suitability for this task.

“…Although these analytical methods are of good analytical performance, these special characteristics would generate serious interference in practical sample analysis. Without effective sample preparation methods, the extremely low contents of targets during the safety analysis of aquatic products would greatly lower the accuracy of the analytical results [14,15]. However, routine sample collection and preparation technologies are time consuming, which usually cost 80% time during the entire analytical process [16][17][18].…”

Safety analysis of aquatic products has been a challenge in recent years due to the serious matrix interference, complex characteristics, and ultra-low content of analytes. Introducing advanced materials to sample preparation technique can greatly improve the extraction, enrichment, and separation for further qualification and quantification of target analytes by coupling with consequent analytical technologies. Based on this scope, this review is mainly introducing advanced materials on the sample preparation for safety analysis of aquatic products in the past decade. After introducing the importance of the corresponding advanced materials, advanced materials are used for the sample preparation and in the improvement of safety analysis result of aquatic products. Advanced materials for sample preparation of aquatic products were reviewed including carbon materials, metal organic frameworks, covalent organic frameworks, molecularly/ions imprinted polymers, etc. Then, applications of the advanced materials for the analysis of specific fishery analytes (antibiotics, anesthetic, preservatives, etc.) were briefly introduced. Conclusions and perspectives on advanced materials for sample preparation and safety analysis of aquatic products were also presented.
