“…In some cases, the adsorbent is the key to the sample preparation technique to improve its sensitivity and reduce the time required by enhancing the enrichment efficiency. The categories of reported adsorbents used for sulfonamide enrichments include carbon materials, polymers, metal organic frameworks (MOFs), covalent organic frameworks (COFs), and so on [16,29,35,[46][47][48][49].…”

“…The term molecularly imprinted polymer was further searched in the results of polymer. As shown, carbon [28,30,40,41,46,[107][108][109][110][111][112][113][114] materials are the most widely used adsorbents for enrichments of sulfonamides. Because the key for efficient enrichments of sulfonamides is to improve the adsorption capacity of the adsorbent, investigations of the adsorption properties and mechanisms are necessary.…”

Sulfonamides in environmental water, food, and feed are a major concern for both aquatic ecosystems and public health, because they may lead to the health risk of drug resistance. Thus, numerous sensitive detection and rapid removal methodologies have been established. This review summarizes the sample preparation techniques and instrumental methods used for sensitive detection of sulfonamides.Additionally, adsorption and photocatalysis for the rapid removal of sulfonamides are also discussed. This review provides a comprehensive perspective on future sulfonamide analyses that have good performance, and on the basic methods for the rapid removal of sulfonamides.

“…All of them present good chemical and thermal stability, as well as mechanical strength, variable electrical conductivity, larger specific surface area and a great capacity to establish π-π interactions [5,6,17]. For these reasons the combination of the advantages brought by these materials with those associated with m-NPs, constitutes a good strategy widely used in sample preparation in the area of food analysis as can be seen in Table 1, in which some of the most recently applications in this field have been compiled [18][19][20][21][22][23][24][25][26][27].…”

Nanotechnology has become a topic of interest due to the outstanding advantages that the use of nanomaterials offers in many fields. Among them, magnetic nanoparticles (m-NPs) have been one of the most widely applied in recent years. In addition to the unique features of nanomaterials in general, which exclusively appear at nanoscale, these present magnetic or paramagnetic properties that result of great interest in many applications. In particular, in the area of food analysis the use of these nanomaterials has undergone a considerable increase since they can be easily separated from the matrix in sorbent-based extractions, providing a considerable simplification of the procedures. This allows reducing cost and giving fast responses, which is essential in the food trade to guarantee consumer safety. These materials can also be easily tunable, providing higher selectivity. Moreover, their particular electrical, thermal and optical characteristics allow enhancing sensor signals, increasing the sensitivity of the approaches based on this type of device. The aim of this review article is to summarise the most remarkable applications of m-NPs in food analysis in the last five years (2016–2020) showing a general view of the use of such materials in the field.

Polyethyleneimine‐modified magnetic multi‐walled carbon nanotubes were developed to extract 10 mycotoxins. Simple modification of polyethyleneimine was achieved on the magnetic substrate by using an epoxy‐containing silane agent as a linker. The resultant magnetic adsorbent was integrated with reverse phase and anion exchange interaction sites. Under optimal extraction conditions, only 20.0 mg adsorbent was used to extract the mycotoxins from 50.0 mL loading solution. The maximum adsorption capacities of the adsorbent toward the mycotoxins ranged from 4.9 to 10.2 mg/g. Adsorption and desorption were completed within 3.0 and 2.0 min, respectively. The adsorbent could be used for six repeated runs without evident change in extraction performance. The adsorbent combined with liquid chromatography–tandem mass spectrometry was applied further to analyze the mycotoxins in milk. The absolute recoveries of the 10 mycotoxins ranged from 88.3 to 103.5% with relative standard deviations that ranged from 2.4 to 6.5%, and their limits of detection were 0.003 to 0.442 μg/kg. The proposed adsorbent has great potential in the routine analysis of mycotoxins in ordinary analytical chemistry laboratory.
