“…Based on current methodologies, sulfonamides have been detected in foods of animal origin [16] and feed [17], as well as in environmental samples [18]. Diverse complex matrices present different physicochemical properties and contain various impurities; thus, different sample preparation techniques are utilized, including magnetic solid-phase extraction (MSPE) [16,[19][20][21][22][23][24][25][26][27][28][29][30][31][32][33][34][35][36] and SPME [37][38][39][40][41][42][43][44][45]. 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.…”

“…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].…”

“…Derived from SPE, MSPE was first proposed in 1999 [83][84][85], which has drawn considerable attention. MSPE based on a magnetic adsorbent was gradually developed for sulfonamide enrichment owing to its high efficiency for separation and pre-enrichment of target compounds from complex matrices [16,[19][20][21][22][23][24][25][26][27][28][29][30][31][32][33][34][35][36]. As shown in Figure 5, magnetic adsorbents are dispersed directly into sample solutions, which increase the contact area between adsorbents and analytes [77] and avoid the time-consuming processes of conventional SPE caused by column packing and large-volume sample loading [20,29,86].…”

“…The π-π stacking and electrostatic attraction between the positively (Figure 6b and c). Similarly, the functional groups in porphyrins have also been integrated with COFs for effective enrichment of sulfadiazine, sulfamerazine, sulfamethazine, sulfamonomethoxine, sulfamethoxazole, and sulfadimethoxine in lake water, milk, pork, chicken, and shrimp samples with good recoveries [35]. By endowing novel materials with magnetism, an easier and faster separation process and a higher contact area during the extraction procedure can be achieved, which provide MSPE with a good ability to effectively enrich sulfonamide from complex matrices.…”

Their fascinating characteristics improve the enrichment performance.…”

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.

Core–shell structures, where the “guest” material is encapsulated within a protective shell, integrate the advantages of different materials to enhance the overall properties of the composite. Covalent–organic frameworks (COFs) are favorable candidates for composing core–shell structures due to their inherent porosity, good activity, excellent stability, and other advantages. In particular, COFs as shells to encapsulate other functional materials are becoming increasingly popular in the fields of environmental remediation and energy conversion. However, there is a lack of reviews on COF‐based core–shell materials. In this context, this review provides a systematic summary of the current research on COF‐based core–shell composites. First, a simple classification is made for COF‐based core–shell composites. The second part of the review describes the main synthesis methods. The changes brought about by the COF shell and core–shell structures on the properties of the composites and their applications in photocatalysis, electrocatalysis, adsorption, sensing, and supercapacitors are then emphasized. Finally, new perspectives on the future development and challenges of composites are presented. The purpose of this study is to provide future insights into the design and application of COF‐based core–shell composites.

Enhancing the specific surface area of stationary phase is important in chromatographic science, especially in open‐tubular column in which the coating only exists on the inner surface. In this work, a porous layer open‐tubular (PLOT) column with stationary phase of styrene and itaconic acid‐copolymerized polymer was developed. Thermal‐initiated polymerization method with strategies like controlling the ratio of reaction reagents to solvents and reaction time, confinement by the narrow inner diameter of capillary were used for preparing the stationary phase with uniform structure and relatively thick layer. Due to the high separation efficiency and capacity, the PLOT column was used for capillary electrochromatography (CEC) separation of multiple groups of analytes like alkylbenzenes, phenyl amines, phenols, vanillins, and sulfonamides with theoretical plates (N) up to 1,54,845 N/m. In addition, due to high permeability of the CEC column and large electroosmotic flow mobility generated by abundant carboxyl groups in the coating material, the PLOT‐CEC column was successfully coupled with mass spectrometry (MS) through a sheath flow interface. The developed PLOT‐CEC‐MS method was used for the analysis of antiseptics like parabens and herbicides like pyridines.
