Abstract

A magnetic covalent organic framework nanomaterial (Fe₃O₄@COFs) served as an adsorbent for enrichment and a new matrix for SALDI-TOF-MS analysis of PAHs and their derivatives in PM_2.5. The unique properties of Fe₃O₄@COFs in terms of high enrichment ability and matrix-free interference made it possible for sensitive analysis of low-concentration organic small-molecule pollutants in complex environmental samples.
