Sorption of Ce(III) on magnetic/olive pomace nanocomposite: isotherm, kinetic and thermodynamic studies

Used for various high-tech applications, cerium is an important rare earth element (REE), and its sorption on solids also considering purification environmental radioactive waste disposal. In view of the industrial terms, it to remove Ce3+ ions from aqueous solution. Magnetite magnetic olive pomace nanocomposite were thus fabricated by a partial reduction co-precipitation approach. The structure morphological properties prepared nano-material characterized means scanning electron microscopy (SEM), transmission (TEM), X-Ray diffraction (XRD), Fourier transform infrared spectrometry (FT-IR), vibrating sample magnetometry (VSM), BET surface area analysis. effects parameters such as solution pH, contact time, initial Ce(III) concentration, temperature efficiency studied. maximum capacities magnetite (MNP) (MOP) found be 76.92 90.90 mgg?1, respectively. data fitted well with Dubinin-Radushkevich isotherm model pseudo-second-order kinetic model. Thermodynamic indicated that was non-spontaneous endothermic. This paper reports preparation MNP novel MOP their application efficient, sustainable adsorbents alternative commercial ones adsorption
