A novel magnetic ion imprinted polymer as a selective magnetic solid phase for separation of trace lead(II) ions from agricultural products, and optimization using a Box–Behnken design

In this work, a magnetic ion-imprinted polymer (Fe3O4@SiO2@IIP) as a novel and selective nanosorbent for selective extraction of Pb(II) ions from various agricultural products is presented. The novel lead magnetic ion-imprinted polymer was synthesized by imidazole as a new ligand and grafted onto the surface of Fe3O4@SiO2 NPs. A Box–Behnken (BBD) design was used for optimization of the extraction and elution steps. In the selected conditions,...
