Abstract

     Graphene oxide (GO) Samples are locally synthesized for use in sorption and radionuclides removal studies of 152+154Eu (III). The samples were characterized by FT-IR, X-ray diffraction (XRD) and electron scanning microscopy (SEM).  These samples are used to study the adsorption of some inorganic acids HCl, HNO3, H2SO4 and H3PO4 as well as organic acetic, oxalic, citric, tartaric and EDTA acids from dilute solutions at low concentrations. The adsorption behavior of 152+154Eu (III) was studied under static conditions. Effects of: pH solution, contact time, particle size, concentration of metal ion and adsorption kinetics temperature are intensively studied in this study.     Thermodynamic parameters such as Gibbs free energy changes (∆G◦), enthalpy (∆H◦) and entropy (∆S◦) are estimated. The adsorption, isotherms and kinetics process was analyzed using various models. In the case of Eu (III), adsorption is found to obey Langmuir isotherm stronger than Freundlich isotherm and the pseudo-second order kinetics mathematics the data for adsorption.
