Abstract

In this study, the structures of lanthanide complexes in organic solvents for minor actinide recovery were evaluated by measuring ion beam induced luminescence (IBIL) of lanthanide complexes with organic solvents using H⁺ and Ar⁸⁺ ion beams. The organic solvent types affected the IBIL spectrum shapes of the lanthanide complexes in the measurements. The shapes of the IBIL spectra of lanthanide complexes in the organic solvent under Ar⁸⁺ ion beam impact were found to be similar to those with the H⁺ ion beam. Additionally, the organic solvent samples were compared with the adsorbent samples to evaluate the spectral shapes of the IBIL. The IBIL spectra of the Eu complexes in the N,N,N’,N’-tetraoctyl diglycolamide (TODGA) solvent recorded with ion beams were found similar in shape to that of the adsorbent. However, the IBIL spectrum of Eu complexes differed in the bis(2-ethylhexyl) hydrogen phosphate (HDEHP) solvent and the HDEHP/SiO₂-P adsorbent. Although Eu³⁺ chemically binds to the O of NO₃⁻ in the TODGA solvent, Eu and HDEHP complexes do not contain NO₃ and Eu³⁺ directly binds to the HDEHP solvent. Therefore, the differences in the Eu complex structures might affect the IBIL spectra in the organic solvent and the adsorbent between HDEHP and TODGA.

氢离子束和氩离子束辐照有机溶剂中镧系配合物的离子束诱导发光

本研究通过使用 H+ 和 Ar8+ 离子束测量有机溶剂中镧系元素络合物的离子束诱导发光 (IBIL)，评估了有机溶剂中用于次要锕系元素回收的镧系元素络合物的结构。在测量中，有机溶剂类型会影响镧系元素络合物的 IBIL 光谱形状。在 Ar8+ 离子束的作用下，有机溶剂中的镧系元素络合物的 IBIL 光谱形状与 H+ 离子束下的相似。此外，还将有机溶剂样品与吸附剂样品进行了比较，以评估 IBIL 的光谱形状。用离子束记录的 N,N,N',N'-四辛基二乙二醇酰胺（TODGA）溶剂中 Eu 复合物的 IBIL 光谱形状与吸附剂的相似。然而，Eu 复合物的 IBIL 光谱在磷酸二（2-乙基己基）氢（HDEHP）溶剂和 HDEHP/SiO2-P 吸附剂中有所不同。虽然 Eu3+ 与 TODGA 溶剂中 NO3- 的 O 发生化学结合，但 Eu 和 HDEHP 复合物中不含有 NO3，Eu3+ 直接与 HDEHP 溶剂结合。因此，Eu 复合物结构的不同可能会影响 HDEHP 和 TODGA 在有机溶剂和吸附剂中的 IBIL 光谱。

期刊介绍： Section B of Nuclear Instruments and Methods in Physics Research covers all aspects of the interaction of energetic beams with atoms, molecules and aggregate forms of matter. This includes ion beam analysis and ion beam modification of materials as well as basic data of importance for these studies. Topics of general interest include: atomic collisions in solids, particle channelling, all aspects of collision cascades, the modification of materials by energetic beams, ion implantation, irradiation - induced changes in materials, the physics and chemistry of beam interactions and the analysis of materials by all forms of energetic radiation. Modification by ion, laser and electron beams for the study of electronic materials, metals, ceramics, insulators, polymers and other important and new materials systems are included. Related studies, such as the application of ion beam analysis to biological, archaeological and geological samples as well as applications to solve problems in planetary science are also welcome. Energetic beams of interest include atomic and molecular ions, neutrons, positrons and muons, plasmas directed at surfaces, electron and photon beams, including laser treated surfaces and studies of solids by photon radiation from rotating anodes, synchrotrons, etc. In addition, the interaction between various forms of radiation and radiation-induced deposition processes are relevant.
