Abstract
A novel magnetic copper-based metal–organic framework (M-MOF) was prepared using a Fe4O3–graphene oxide (GO)–β-cyclodextrin (β-CD) nanocomposite as the magnetic core and support, and used for adsorption and removal of neonicotinoid insecticide pollutants from aqueous solution. M-MOF characterization suggested that 1Fe4O3–GO–β-CD consisted of a thin single layer with anchored Fe3O4. The M-MOF was coated on the Fe4O3–GO–β-CD surface. The M-MOF had a large Brunauer–Emmett–Teller surface area (250.33m2g−1) and high super-paramagnetism with saturation magnetization of 10.47emug−1. Adsorption model analysis showed that the equilibrium data for thiacloprid fitted Langmuir monolayer adsorption and the other insecticides tested showed Freundlich bimolecular layer adsorption. The results show that M-MOF is a promising hybrid adsorbent for rapid removal of neonicotinoid insecticide pollutants from environmental waters.
