| abstract | The invention discloses a solid-phase microextraction device and a preparation method thereof, belonging to the cross field of analytical chemistry and environmental chemistry. The solid-phase microextraction device adopts a novel composite coating of crystalline porous polymer and epoxy resin as a functional extraction head, and the solid-phase microextraction efficiency of pyrethroid pesticides is significantly improved by utilizing the synergistic effect of crystalline porous polymer and epoxy resin. The extraction efficiency of various commercial SPME extractors can reach 1.5-150 times. Therefore, the sensitivity of detection of pyrethroid substances is significantly improved, and the qualitative and quantitative detection of pyrethroid pesticides in water is well realized. |
