“…Compared with traditional liquid-liquid extraction (LLE) methods, it can improve the recovery rate of analytes, separate analytes from interfering components more effectively, and reduce sample pretreatment processes [49]. Moreover, it shows high enrichment and cleaning-up capacities, low consumption of reagents, and easy operation, and has been widely used in many fields such as medicine, food, environment, commodity inspection, and the chemical industry [50]. Although these technologies have been widely applied, achieving the optimal extraction rate is currently a challenge [51].…”

Deep eutectic solvents (DESs), as a new type of eco‐friendly solvent, have attracted increasing attention on the extraction and separation of flavonoid compounds from various samples, owing to their excellent properties such as biodegradability and ease of handling with very low toxicity. This article provides a status review of the applications of DESs in the extraction of flavonoids, including the introduction of flavonoid compounds, the properties and superiority of DESs, and extraction methods (ultrasonic‐assisted extraction, heating reflux extraction, matrix solid‐phase dispersion, and solid‐phase extraction). Finally, prospects and challenges in the application of DESs on extraction and separation are extensively elucidated and critically reviewed.

“…The extraction, separation, and cleanup of various analytes from complicated matrices are accomplished with this technology, which is based on the dispersion of a solid sorbent in liquid samples . It is regarded as a micro- and macroscale method of extraction and cleaning . Target analytes are adsorbed to the surface of the adsorbent dispersion in the solvent in dispersive solid-phase extraction (d-SPE), which includes adding adsorbents to the sample solution rather than placing them inside the SPE column.…”

The majority of pharmaceuticals are found in the environment as mixtures. However, a significant amount of these therapeutic compounds cannot be completely metabolized by the human body; thus, they are excreted through feces and urine and end up in wastewater treatment plants (WWTPs). The presence of pharmaceuticals and the degree to which they can be removed during wastewater treatment are now important research topics. Despite the adoption of various alternative technologies for the treatment of wastewater, the adsorption process is still regarded as a promising method due to its high efficiency, increased simplicity, and lower costs. Recent developments in the adsorption process involve the incorporation of an artificial molecularly imprinted polymer (MIP), which is a potent molecular receptor capable of selectively recognizing and removing pollutants. The MIP has advantageous characteristics, which include high affinity, predetermination, high stability, ease of preparation, and low cost. Notably, MIPs can be applied to the cleanup and preconcentration of analytes as the selective adsorbent of solid-phase extraction (SPE), magnetic solid phase extraction (MSPE), and dispersive solid-phase extraction (dSPE). Furthermore, MIPs can be produced as composite nanomaterials by employing nanoparticles (nanoMIP). The advancements of MIPs employed as sorbent materials for quantitative assessment and purification of pharmaceuticals in environmental water have been given most of the focus. Therefore, this study not only aims to present the fundamental ideas about the application of MIPs as sorbents but also gives an overview of the considerable initiatives made in recent years to enhance the performance of MIPs. Considering this, various current approaches to the development of MIP-based extraction techniques are detailed in the present review. This review also demonstrates how kinetics, thermodynamics, and isotherm models can be used to better understand the behavior of adsorbents and the adsorption process.

“…One major challenge is improving selectivity in complex real-world samples containing interfering compounds. Techniques like liquid-liquid extraction [97,98] or solid-phase extraction [99,100] are used to isolate BPA from complex sample matrices. This removes potential interferents and concentrates BPA for improved detection.…”

Bisphenol A (BPA) is an industrial chemical used extensively in plastics and resins. However, its endocrine-disrupting properties pose risks to human health and the environment. Thus, accurate and rapid detection of BPA is crucial for exposure monitoring and risk mitigation. Molecularly imprinted electrochemical sensors (MIES) have emerged as a promising tool for BPA detection due to their high selectivity, sensitivity, affordability, and portability. This review provides a comprehensive overview of recent advances in MIES for BPA detection. We discuss the operating principles, fabrication strategies, materials, and methods used in MIES. Key findings show that MIES demonstrate detection limits comparable or superior to conventional methods like HPLC and GC-MS. Selectivity studies reveal excellent discrimination between BPA and structural analogs. Recent innovations in nanomaterials, novel monomers, and fabrication techniques have enhanced sensitivity, selectivity, and stability. However, limitations exist in reproducibility, selectivity, and stability. While challenges remain, MIES provide a low-cost portable detection method suitable for on-site BPA monitoring in diverse sectors. Further optimization of sensor fabrication and characterization will enable the immense potential of MIES for field-based BPA detection.
