چكيده فارسي :
Metal organic frameworks (MOFs) and porous hybrid polymer–metal composites at the nanoscale, are recent innovations in the field of chemistry. MOFs are nanoporous materials, consisting of metal ions linked together by organic bridging ligands. In the present study, we report the application of HKUST-1@Graphene Oxide as a novel adsorbent for the fast removal of Pb(II) ions from aqueous solution in view of adsorption isotherms, kinetics, thermodynamics, and adsorbent regeneration. The adsorbent was characterized by FT-IR, XRD, SEM and N2 adsorption/desorption measurement. The adsorption data follows pseudo-second-order kinetics model and fits the Freundlich adsorption model. The used HKUST-1@GO nanocomposites are regenerated effectively and recycled at least four times without significant loss of adsorption capacity.
