Lanthanides/actinides sorption speciation on minerals and oxides by means of time resolved laser fluorescence spectroscopy (TRLFS), extended X-ray absorption fine structure spectroscopy (EXAFS) and density functional theory (DFT) is reviewed in the field of nuclear disposal safety research. The theoretical aspects of the methods are concisely presented. Examples of recent research results of lanthanide/actinide speciation and local atomic structures using TRLFS, EXAFS and DFT are discussed. The interaction of lanthanides/actinides with oxides and minerals as well as their uptake are also of common interest in radionuclide chemistry. Especially the sorption and inclusion of radionuclides into several minerals lead to an improvement in knowledge of minor components in solids. In the solid-liquid interface, the speciation and local atomic structures of Eu(III), Cm(III), U(VI), and Np(IV/VI) in several natural and synthetic minerals and oxides are also reviewed and discussed. The review is important to understand the physicochemical behavior of lanthanides/actinides at a molecular level in the natural environment.
镧系元素/锕系元素在矿物和氧化物上的吸附形态、价态通过时间分辨激光荧光光谱（TRLFS）、扩展 X 射线吸收精细结构光谱（EXAFS）和密度泛函理论（DFT）进行研究，这是在核废料安全研究领域。本文简要介绍了这些方法的理论方面。讨论了使用 TRLFS、EXAFS 和 DFT 对镧系元素/锕系元素形态和局部原子结构的最新研究结果。镧系元素/锕系元素与氧化物和矿物的相互作用及其摄取也是放射性核素化学的共同关注点。特别是放射性核素被几种矿物吸附和包裹，这使得对固体中少量成分的了解得到了提高。在固-液界面，Eu(III)、Cm(III)、U(VI)和 Np(IV/VI)在几种天然和合成矿物和氧化物中的形态和局部原子结构也进行了综述和讨论。这篇综述对于在自然环境中从分子水平理解镧系元素/锕系元素的物理化学行为非常重要。
