Graphene oxide/chitosan/zirconiumphosphate/silicate (GO/CS/ZrP/Si) as a novel nano-composite has highly adsorption of Cs-134, Co-60, Eu-152,Eu- 154 and (160) Tb. The GO/CS/ZrP/Si has better adsorption of Eu-152,Eu- 154 and (160) Tb. A comparison of the adsorption kinetics and isotherms were analyzed using different models. The adsorption data was fitting with the pseudo second-order and the Langmuir isotherm. The changes in Gibbs free energy Delta G(o)), enthalpy (Delta H-o), and entropy (Delta S-o) have been calculated. Selective adsorption of lanthanide ions from monazite solution was achieved. The break through capacities of Sm3+, La3+, Eu3+ and Tb3+ on GO/CS/ZrP/Si were found as 14.5, 13.0, 14.8 and 14.9 mg/g respectively.
