英文摘要:

      With the increasing attention to food safety and environmental quality, efficient and accurate pollutant detection technology is crucial. Supramolecular solvent microextraction technology, as an emerging sample pretreatment method, has demonstrated unique advantages in the field of food and environmental pollutant detection due to its high efficiency, good selectivity and environmental friendliness. This technology is based on the selective recognition and enrichment ability of specific pollutants by supramolecular solvents (such as nano/micro scale solvents formed by host molecules such as cyclodextrin and crown ether), and achieves rapid separation and concentration of target substances in samples through microextraction operations. As a new type of green solvent, supramolecular solvents have high extraction efficiency, wide polarity range, customizable structure, and both extraction and purification effects, making them widely used in the field of extraction and separation. This review introduced the properties of supramolecular solvents and types of supramolecular solvent microextraction, with a focus on the detailed application of this technology in the detection of food and environmental pollutants, and provided prospects for the work in this field, in order to provide reference for the promotion and application of supramolecular solvent-microextraction technology.
