Nano-MgO particles were made for the adsorption of UO22+ from aqueous solutions. The obtained MgO nanoparticles were characterized by FTIR, XRD and SEM. The adsorption of UO22+ by particle was optimized with RSM. Coefficients of correlation (R-2 = 0.99) and probability F-values (F = 3.1 10(-10)) reveal that the model is very good for the experimental data. Under optimum conditions, the adsorption capacity of nano-MgO particles was found to be 128.4 mg g(-1). The results showed that nano-MgO particles were suitable for the sorption of UO22+ ions from aqueous solutions. In addition, the adsorption isotherms and the thermodynamic parameters were examined.
