摘要

采用共沉淀法制备了层状Fe/Ba/Mg三元金属氢氧化物，以去除水中的U（VI）。采用多种方法对Fe/Ba/Mg复合材料进行了表征，并考察了其在水溶液中的脱除U（VI）性能。Fe/Ba/Mg三元金属氢氧化物对U（VI）的去除率为436.68 Mg·g−1。其他共存离子的存在对U（VI）去除能力的影响可以忽略不计。Fe/Ba/Mg复合材料对U（VI）的吸附是一个自发吸热过程。研究结果表明，Fe/Ba/Mg三元氢氧化铁在处理含铀废水中具有良好的应用前景。图形抽象

Efficient removal of uranium from aqueous solutions using a layered ternary Fe/Ba/Mg metal hydroxide

A layered ternary Fe/Ba/Mg metal hydroxide was prepared via the co-precipitation method to remove U(VI) from aqueous solutions. The Fe/Ba/Mg composite was characterized using various methods, and its U(VI) removal performance was investigated in aqueous solutions. The ternary Fe/Ba/Mg metal hydroxide exhibited a U(VI) removal capacity of 436.68 mg·g⁻¹. The presence of other coexisting ions negligibly affected the U(VI) removal capacity. The adsorption of U(VI) by the Fe/Ba/Mg composite was a spontaneous and endothermic process. This study demonstrates the good application prospects of the ternary Fe/Ba/Mg metal hydroxide in the treatment of uranium-containing wastewater.
