Abstract

Comparative analysis of the sorption ability of the obtained carbonate forms of layered double hydroxides with different Ni(II)/Fe(III) ratio and their magnetic nanocomposites toward ${{\text{UO}}}_{2}^{2+}$ ions in aqueous solutions is performed. The synergistic effect of magnetic composite sorbents based on layered double hydroxides and magnetite on the removal uranyl ions in a wide pH range (3.5-9.5) is shown. Due to the high efficiency in combination with magnetic solid-phase separation, the obtained adsorption materials are promising for the purification of uranium-containing natural and wastewaters.

镍(II)/铁(III)层状双氢氧化物及其磁性纳米复合材料吸附去除水溶液中的 $${{text{UO}}}_{2}^{2+}$ 离子

比较分析了所获得的不同镍（II）/铁（III）比的碳酸盐形式的层状双氢氧化物及其磁性纳米复合材料对水溶液中${text{UO}}}_{2}^{2+}$离子的吸附能力。结果表明，在较宽的 pH 值范围（3.5-9.5）内，基于层状双氢氧化物和磁铁矿的磁性复合吸附剂对铀酰离子的去除具有协同效应。由于与磁性固相分离相结合具有很高的效率，所获得的吸附材料有望用于净化含铀的天然水和废水。
