<p>Magnetic graphene oxide nanocomposites (M-GO) were successfully synthesized by partial reduction co-precipitation method and used for removal of Sr(II) and Cs(I) ions from aqueous solutions. The structures and properties of the M-GO was investigated by X-ray diffraction, Fourier transformed infrared spectroscopy, X-ray photoelectron spectroscopy, transmission electron microscopy, scanning electron microscopy, vibrating sample magnetometer (VSM) and N<sub>2</sub>-BET measurements. It is found that M-GO has 2.103 mg/g and 142.070 mg/g adsorption capacities for Sr(II) and Cs(I) ions, respectively. The adsorption isotherm matches well with the Freundlich for Sr(II) and Dubinin–Radushkevich model for Cs(I) and kinetic analysis suggests that the adsorption process is pseudo-second-ordered.</p>

Graphene oxide (GO) and two magnetic graphene oxide (MGO) composites with a different amount of magnetite were synthesized, characterized and used in sorption experiments. The effect of pH on sorption of Am(III) and Pu(IV) isotopes as well as Co(II), Ni(II), Cu(II) and Pb(II) to GO and MGO was studied in equilibrium and kinetic experiments. The adsorption capacities varied from 30 to 574 mg g -1 while rate constants ranged from 0.29 to 0.46 min -1 and increased in the following order Co, Cu, Pb and Ni. Large variations in the uptake of studied elements by adsorbents depending on initial and final pH of solutions were observed.

Used for various high-tech applications, cerium is an important rare earth element (REE) and its sorption on various solids also important considering purification, environmental and radioactive waste disposal, In view of the industrial and environmental terms, it is important to remove Ce 3+ ions from an aqueous solution. Magnetite and magnetic olive pomace nanocomposite were thus fabricated by a partial reduction co-precipitation approach.The structure and morphological properties of the prepared nano-material and nanocomposite were characterized by means of scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-Ray diffraction (XRD), Fourier transform infrared spectrometry (FT-IR), Vibrating Sample Magnetometry (VSM) and BET surface area analysis. The effects of parameters such as solution pH, contact time, initial Ce(III) concentration and temperature on the sorption efficiency were studied. The maximum sorption capacities of the magnetite (MNP) and magnetic olive pomace nanocomposite (MOP) for Ce(III) ions were found to be 76.92 and 90.90 mgg -1 , respectively. The sorption data fitted well with Dubinin-Radushkevich isotherm model and the pseudo-second order kinetic model. Thermodynamic parameters indicated that the sorption was non-spontaneous and endothermic. The present study introduced MNP and MOP as efficient, sustainable adsorbents alternative to commercial ones in wastewater treatment.
