The invention discloses a magnetic fullerene nanomaterial and its application in the magnetic dispersion solid phase extraction of methyl methoxyacrylate pesticides . The nanoparticles were modified to obtain superparamagnetic particles of ferric oxide coated with silica, which were denoted as Fe 3 O 4 @SiO 2 nanoparticles; then Fe 3 O 4 @SiO 2 nanoparticles were mixed with 3-chloropropyltrimethyl oxysilane reaction to obtain Fe 3 O 4 @SiO 2 @Cl nanoparticles; finally, fullerene C 60 was reacted with benzaldehyde and benzylamine to obtain 2,5-diphenylfullerene pyrroline, which was then combined with Fe 3 The reaction of O 4 @SiO 2 @Cl nanoparticles is to obtain magnetic fullerene nanomaterials, which are denoted as Fe 3 O 4 @SiO 2 @C 60 nanoparticles. The magnetic fullerene nanomaterial of the invention can be used for the magnetic dispersion solid phase extraction of methyl methoxyacrylate pesticides, and has strong adsorption, large adsorption capacity, good selectivity and easy elution. |
