“…MIL‐101(Cr) showed a high extraction rate in nonpolar solvent compared with other MOFs. The results indicated that the proposed method in this research had high selectivity and sensitivity, and the method could be applied to extract pesticide residues in high‐fat samples (Li et al., 2015). UiO‐66 has been also applied to determine the organophosphorus pesticide in vegetable oils.…”

“…Hydrogen bonding, π‐π interaction, and hydrophobic interaction between Cotton@UiO‐66 and pesticides were suggested as the main mechanism for the favorable adsorption of four pesticides (Su et al., 2020). Studies have shown that MIL‐101(Zn) has higher adsorption, clean‐up efficiency in nonpolar solution than traditional adsorbent (Li et al., 2015). In order to extract the target analyte from a complex food substrate containing high amounts of lipids and proteins, Zhang and coworkers used MIL‐101(Zn) as adsorbents to extract and separate metazachlor, propanil, pretilachlor, and butachlor in three beans.…”

Pesticide residues in food matrices, threatening the survival and development of humanity, is one of the critical challenges worldwide. Metal–organic frameworks (MOFs) possess excellent properties, which include excellent adsorption capacity, tailorable shape and size, hierarchical structure, numerous surface‐active sites, high specific surface areas, high chemical stabilities, and ease of modification and functionalization. These promising properties render MOFs as advantageous porous materials for the extraction and detection of pesticides in food samples. This review is based on a brief introduction of MOFs and highlights recent advances in pesticide extraction and detection through MOFs. Furthermore, the challenges and prospects in this field are also described.

“…Among these, it is worthy of mention the combination of MAE with dispersive solid phase micro-extraction (D-µ-SPE), till now not applied to hydrocarbon contaminants but successfully applied to the extraction of pesticides [16,17], antibiotic residues [18] and mycotoxins [19] from a wide range of food. The combination of MAE (more precisely MAS, because a basic hydrolysis is performed) with dispersive liquid-liquid micro-extraction (DLLME) is for sure the most utilized method, for extraction/purification of food contaminants, particularly of hydrocarbon contaminants (as detailed in the next paragraphs).…”

Due to food complexity and the low amount at which contaminants are usually present in food, their analytical determination can be particularly challenging. Conventional sample preparation methods making use of large solvent volumes and involving intensive sample manipulation can lead to sample contamination or losses of analytes. To overcome the disadvantages of conventional sample preparation, many researchers put their efforts toward the development of rapid and environmental-friendly methods, minimizing solvent consumption. In this context, microwave-assisted-extraction (MAE) has obtained, over the last years, increasing attention from analytical chemists and it has been successfully utilized for the extraction of various contaminants from different foods. In the first part of this review, an updated overview of the microwave-based extraction technique used for rapid and efficient extraction of organic contaminants from food is given. The principle of the technique, a description of available instrumentation, optimization of parameters affecting the extraction yield, as well as integrated techniques for further purification/enrichment prior to the analytical determination, are illustrated. In the second part of the review, the latest applications concerning the use of microwave energy for the determination of hydrocarbon contaminants—namely polycyclic aromatic hydrocarbons (PAHs) and mineral oil hydrocarbons (MOH)—are reported and critically overviewed and future trends are delineated.

“…Under the optimized condition, herbicides were determined by the MIL-101based D-μ-SPE-HPLC with low LODs (0.585-1.04 μg/L) and good recoveries (87.3-107%). To enhance extraction performance and accelerate analytes' transfer from sample matrix to solvent, Li et al [82] described nonpolar solvent dynamic microwave assisted extraction (MAE) combining with MIL-101 based D-μ-SPE for separation of herbicides in soybeans. Based on HPLC analysis, this extraction method was proved to be rapid and effective (extraction time: 5 min) with recoveries in the range of 91.1-106.7%.…”

Metal-organic frameworks are promising materials in diverse analytical applications especially in sample pretreatment by virtue of their diverse structure topology, tunable pore size, permanent nanoscale porosity, high surface area, and good thermostability. According to hydrostability, metal-organic frameworks are divided into moisture-sensitive and water-stable types. In the actual applications, both kinds of metal-organic frameworks are usually engineered into hybrid composites containing magnetite, silicon dioxide, graphene, or directly carbonized to metal-organic frameworks derived carbon. These metal-organic frameworks based materials show good extraction performance to environmental pollutants. This review provides a critical overview of the applications of metal-organic frameworks and their composites in sample pretreatment modes, that is, solid-phase extraction, magnetic solidphase extraction, micro-solid-phase extraction, solid-phase microextraction, and stir bar solid extraction.
