“…The amount of sorbent, sample volume, LODs, and other factors were compared with other previously reported methods for the measurement of trace SAs in food samples [1,10,19,[34][35][36][37]. As seen in Table 2, our method has many advantages, such as less sample volume, relatively lower LODs, and better recoveries.…”

“…However, with the increasing test demand for analytes, the commercial kinds of SPE adsorbents are very limited. Based on this, many kinds of porous materials have been studied as SPE adsorbents, including metal-organic frameworks [8], graphene [9], molecularly imprinted resins [10], ordered mesoporous silica materials [11], ionic liquids [12], etc. However, these materials also have some disadvantages, such as tedious synthesis conditions, environmental pollution, poor structural stability, and so on.…”

In this article, a highly crystalline porous imine‐based covalent organic framework was synthesized at room temperature and used as solid‐phase extraction (SPE) adsorbent for the purification and enrichment of trace sulfonamides (SAs) from food samples. The structure of the obtained material was characterized and studied in detail. The extraction process was optimized and the final elution was determined by the ultra‐high‐performance liquid chromatography‐quadrupole time of flight mass spectrometry method. Low limits of detection (0.02–0.19 μg/kg) were obtained under optimal conditions, with the recoveries ranging from 70.5% to 105.3% when spiked at different levels. The adsorption process of the material for SAs was fitted by the Langmuir and Freundlich adsorption isotherm model, and the extraction capacity for Nitrofuran metabolites from food samples was also investigated for comparison. The results demonstrated that the framework was a good candidate SPE adsorbent that can be used for the enrichment of drug residues in complex matrix, and the work may provide a systematic study method for the development of porous adsorbents.

“…The time consumed by sample pre-treatment usually accounts for more than two-thirds of the whole analytical cycle, which is the key to obtaining accurate results. At present, liquid–liquid extraction (LLE) [ 12 , 13 , 14 ] and solid-phase extraction (SPE) [ 15 , 16 , 17 ] are the main pre-treatment and purification methods for determining antibiotic residues in biological samples. SPE removes impurities quickly and effectively and uses fewer organic solvents compared to LLE [ 18 ].…”

The amount of macrolide (MAL) residues in aquatic products, including oleandomycin (OLD), erythromycin (ERM), clarithromycin (CLA), azithromycin (AZI), kitasamycin (KIT), josamycin (JOS), spiramycin (SPI), tilmicosin (TIL), tylosin (TYL), and roxithromycin (ROX), was determined using solid-phase extraction and ultra-performance liquid chromatography–tandem mass spectrometry (UPLC-MS/MS). The residues were extracted with 1% ammonia acetonitrile solution and purified by neutral alumina adsorption. Chromatographic separation was completed on an ACQUITY UPLC BEH C18 column with acetonitrile–0.1% formic acid aqueous solution as the mobile phase, and mass spectrometry detection was performed by multiple reaction monitoring scanning with the positive mode in an electrospray ion source (ESI+). Five isotopically labeled compounds were used as internal standards for quality control purposes. The findings indicated that across the mass concentration span of 1.0–100 μg/L, there was a strong linear correlation (R2 > 0.99) between the concentration and instrumental response for the 10 MALs. The limit of detection of UPLC-MS/MS was 0.25–0.50 μg/kg, and the limit of quantitation was 0.5–1.0 μg/kg. The added recovery of blank matrix samples at standard gradient levels (1.0, 5.0, and 50.0 μg/kg) was 83.1–116.6%, and the intra-day precision and inter-day precisions were 3.7 and 13.8%, respectively. The method is simple and fast, with high accuracy and good repeatability, in line with the requirements for accurate qualitative and quantitative analysis of the residues for 10 MALs in aquatic products.

“…28 HMIRs have been applied to extract and separate metal ions, pollutants, proteins, etc ., in aqueous matrices. 29,30 However, it is worth noting that formaldehyde is often used as a crosslinker, and phenol and resorcinol are commonly employed as monomers in the resin preparation process. Formaldehyde is a first-class carcinogen with serious teratogenic and carcinogenic effects.…”
