Abstract

The application discloses a molecularly imprinted cotton fiber membrane for selectively capturing synthetic cannabinoids, a preparation method and application thereof. The molecularly imprinted cotton fiber membrane is first subjected to an ammoniation functional treatment on the surface of the degreasing cotton through an in-situ polymerization mode, and then metal ions and functional monomers are introduced to realize construction of a molecularly imprinted structure, so that the material with the recognition performance is obtained. The material is simple in chemical modification, low in preparation cost, good in repeatability and stability, and strong in capturing selectivity, and realizes selective capturing of trace synthetic cannabinoid drugs in exhaled gas and atmospheric samples.
