摘要

The magnesium aluminate (MgA) composite was developed and able successfully to remove Cs(I) and Eu(III) from radioactive waste solution. In this study batch technique was followed at varying temperature ranges, and contact time on cesium and europium uptake. The experimental findings demonstrated that the Langmuir isotherm model fits the adsorption data quite well. The adsorption capacities for Eu(III) and Cs(I) are 181.9 and 69.6 mg g−1, respectively at 25 °C. The pseudo-second-order rate equation is followed by the adsorption processes. The removal processes are endothermic and spontaneous. Finally, MgA is recommended for protection the environment from investigated long-lived hazardous radionuclides.
