Abstract
The application of Metal- organic frameworks (MOFs) of zinc and copper-based materials for the removal of Fluorene is reported in this paper. The copper and zinc Benzene 1,4-Dicarboxylic acid (BDC) (Zn-BDC and Cu-BDC) MOFs were synthesized using refluxing method, and characterized using Fourier transform infrared spectroscopy (FTIR), Scanning electron microscopy (SEM), High resolution transmission electron microscopy (HR-TEM), X-ray diffraction (XRD) and energy dispersive spectroscopy (EDS) techniques. The adsorption of fluorene was favorable with both Zn-BDC and Cu-BDC MOFs. The data were investigated by the Langmuir, Freundlich and Temkin adsorption isotherm and the adsorption kinetics follows the pseudo second order kinetics model with reference to the correlation data obtained. The thermodynamic study showed that the sorption of Fluorene was spontaneous with both ZnBDC and Cu-BDC MOFs over the temperature range studied. The MOFs materials were found to be stable over a wide temperature range and the desorption/reusability experiment showed that the MOFs demonstrated excellent reusability capacity for three batch adsorption process.
