Abstract:
The magnetic sugarcane peel carbonized material CoFe2O4@CSC is successfully prepared on the basis of the hybrid calcination method. The crystal structure,surface morphology and magnetism of the material are characterized by XRD,TEM,SEM and VSM analysis. The results of magnetic solid phase extraction of four pyrethroid insecticides show the best conditions:the amount of material is 40 mg,the pH is 7.0,the equilibrium time is 10 min,and acetonitrile is selected as the eluent. The recovery rate can reach 100.44%,99.74%,96.82% and 99.22%. After the material recycles 6 times,the effect does not decrease significantly. The test of environmental water samples show that the established method has good accuracy and reliability.
