چکیده انگلیسی
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 (250.33 m2 gâ1) and high super-paramagnetism with saturation magnetization of 10.47 emu gâ1. 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.
