Magnetic mesoporous Fe₃O₄@nSiO₂@mSiO₂ nanoparticles for high-throughput mass spectrometry detection of hydrolyzed products of organophosphorus nerve agents

Abstract

A QuEChERS method based on a novel magnetic nanomesoporous material was developed for the efficient extraction of methyl phosphonates in the environment and the analysis of 70 environmental samples could be completed within 20 min.
