Magnetic graphene oxide/double template ion imprinted polymer (MA/MGO@DIIP) was prepared by microwave-assisted inverse emulsion-suspension polymerization. Solid-phase extraction performance of Cd(II) and Cu(II) of MA/MGO@DIIP in vegetables was studied. Cu²⁺ and Cd²⁺ were used as template ions, AM as functional monomer, GO as carrier and Fe3O4 as magnetic component. The samples were characterized by SEM and FTIR. The extraction conditions were optimized as follows: the concentration of HCl in eluent was 0.5 mol/L, the volume was 3 mL, the concentration of sample was 10 μg/L, the volume was 5 mL, pH=7, the flow rate was 2 mL/min, the recovery rate was the highest. When 2% NaCl was added, the extraction efficiency could be improved. In the mixed matrix environment, the extraction efficiency is hardly affected by external ions. After five cycles of adsorption and desorption, the extraction efficiency had no significant effect. The LOD values of Cu²⁺ and Cd²⁺ were 1.67%~5.41% and 3.77%~8.33%, respectively, indicating that the method has good accuracy and reliability, and is a kind of adsorbent with wide application prospect.
