Abstract

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.

Mg-Al二元金属氧化物复合材料对液相Cs(l)和Eu（ll）的吸附性能研究

研制了铝酸镁（MgA）复合材料，成功地去除了放射性废液中的铯(I)和铕（III）。本研究采用间歇式工艺，在不同温度范围和接触时间下对铯和铕的吸收进行了研究。实验结果表明，Langmuir等温线模型与吸附数据吻合较好。在25℃时，对Eu（III）和Cs(I)的吸附量分别为181.9 mg g−1和69.6 mg g−1。吸附过程遵循伪二级速率方程。去除过程是吸热自发的。最后，建议将MgA用于保护环境免受所调查的长寿命有害放射性核素的影响。
