Outline
Magnetic solid-phase extraction (MSPE) has been widely applied in the field of pesticide residue pretreatment due to its advantages of high sensitivity, high selectivity, high accuracy and reusability. Its core component, magnetic nanoparticles (MNPs), possess high specific surface area, excellent biocompatibility, modifiable properties, stable chemical performance and ideal dispersibility, and can efficiently extract various types of pesticides. This paper focused on the application practices of MSPE technology in the detection of different categories of pesticide residues and systematically summarized the research progress of this technology in food and environmental fields in recent years.By considering the structural characteristics and interaction mechanisms of magnetic nano-adsorbents in terms of material composition, physicochemical properties and modification strategies, the interaction mechanisms between MSPE and various target pesticides were further elucidated, so as to provide theoretical support for the technical optimization and scenario adaptation. Meanwhile, it thoroughly discussed the existing problems of MSPE technology in pesticide residue detection and prospects its development, offering a reference for subsequent related research and practice.
