摘要:

磁性纳米材料具有较强的化学稳定性、可再生回收、良好的吸附性能和易于分离等优点,在去除水溶液中的铀酰离子方面有广泛的应用前景。然而,磁性纳米材料也存在易团聚、易氧化等不足,通过表面修饰或改性等方法可改善其不足,提高其对废水中铀酰离子的去除能力,改善其吸附效果。本文通过总结近年来的相关研究资料,概括了磁性纳米材料的种类,归纳总结并比较了不同种类磁性纳米材料对含铀废水的去除能力及优势与不足,探讨了磁性纳米材料在含铀废水处理中的应用并对其机理进行了分析,阐述了磁性纳米材料去除溶液中铀酰离子的影响因素,简述了目前磁性纳米材料在处理含铀废水中有待解决的问题,并对其在分离放射性元素方面的应用前景进行了展望。

Abstract:

Magnetic nanomaterials have many advantages, such as strong chemical stability, good adsorption performance and easy separation and recycling, so they have broad application prospects in removing uranyl ions from water. However, magnetic nanomaterials also have shortcomings such as easily aggregated and oxidized, which yet can be overcome by modification. In this paper, different magnetic nanomaterials are introduced by their categories, and their advantages and disadvantages as well as the ability in removing uranium from wastewater are summarized and compared. Further, the application of magnetic nanomaterials in the treatment of uranium-containing wastewater is discussed and the mechanism is analyzed. Additionally, the influencing factors and the problems in treating uranium-containing wastewater by magnetic nanomaterials are briefly described, and the application trend of magnetic nanomaterials in the separation of radioactive elements is prospected.

Key words: magnetic nanomaterials, separation, uranyl ion, wastewater, environment, adsorption
