ABSTRACT Nanoplastics (NPs) are emerging water contaminants that threaten human health and ecological security. Developing a method for detecting NPs is significant because of their biological toxicity mobility. In this study, magnetic solid‐phase extraction (MSPE) combined with pyrolysis gas chromatography‐mass spectrometry (Py‐GC/MS) was used the pretreatment qualitative detection in complex matrices to avoid sample dissolution eluent usages. The developed methodology can quickly achieve low limits tap river water, 0.7283 0.6474 µg/L, respectively. To enrich biochars derived from cornstalks (Fe 3 O 4 /BCs, i.e., Fe /YMG /YMG‐ZnCl 2 ) were conveniently fabricated using activation coprecipitation methods employed as adsorbents MSPE. results indicated incorporation into BC not only rendered it but also enhanced diversity its surface functional groups adsorption sites, making suitable demonstrated excellent enrichment capacity polystyrene (PSNPs) over various competitive species. Additionally, exhibited good resistance pH anions, reaction mechanism verified kinetics isothermal models. addition, after extracting PSNPs , they successfully qualitatively analyzed by Py‐GC/MS.
