Abstract

Nanostructured cerium oxide (CeO₂) with various morphologies, including nanoparticles, nanorods, and mixture thereof, was synthesized for the purpose of removing uranium (U(VI)) from aqueous solutions. The influence of the morphology of nanostructured CeO₂ on its adsorption performance for uranium was investigated. Additionally, several factors affecting the adsorption experiments—such as pH, initial U(VI) concentration, and contact time—were thoroughly examined. The results demonstrated that nanostructured CeO₂ exhibit rapid (30 min to reach equilibrium) and high adsorption capacities (up to 561.22 mg⋅g⁻¹ for nanoparticles, 408.48 mg⋅g⁻¹ for nanorods, and 507.62 mg⋅g⁻¹ for mixture).

各种纳米结构氧化铈高效吸附铀的构建

合成了具有不同形态的纳米结构氧化铈（CeO2），包括纳米颗粒、纳米棒及其混合物，用于从水溶液中去除铀（U(VI)）。研究了纳米结构CeO2的形貌对其吸附铀性能的影响。此外，还研究了影响吸附实验的几个因素，如pH、初始U（VI）浓度和接触时间。结果表明，纳米结构的CeO2具有快速（30 min即可达到平衡）和高吸附能力（纳米颗粒吸附561.22 mg⋅g−1，纳米棒吸附408.48 mg⋅g−1，混合物吸附507.62 mg⋅g−1）。图形抽象
