本说明总结了我们和其他人最近在未来欧洲核废物管理战略背景下开发用于分离核废物流中锕系元素和镧系元素的配体的工作。简要讨论了世界范围内锕系/镧系元素分离的现状，并介绍了过去20年来欧洲不同类别的杂环软N-和S-供体配体的合成、开发和测试。这项工作导致了目前的基准配体，显示出许多工业用途的理想品质。还讨论了通过配体设计提高辐解稳定性。1引言和背景2二硫代膦酸3 2，2 '：6 '，2“-三联吡啶（TERPY）及相关配体4 2，4，6-三-2-吡啶基-1，3，5-三嗪（TPTZ）及相关配体5 2，6-双（benzoxazole-2-yl）-4-dodecyloxy pyridine（BODO）and Related Ligands 6 Podand Ligands 7 2，6-Bis（1，2，4-三嗪-3-基）吡啶（BTP）和相关配体8 6，6 '-双（1，2，4-三嗪-3-基）-2，2'-联吡啶（BTBP）和相关配体9通过配体设计提高辐解稳定性10结论和展望
This account summarizes recent work by us and others on the development of ligands for the separation of actinides from lanthanides contained in nuclear waste streams in the context of a future European strategy for nuclear waste management. The current status of actinide/lanthanide separations worldwide is briefly discussed, and the synthesis, development, and testing of different classes of heterocyclic soft N- and S-donor ligands in Europe over the last 20 years is presented. This work has led to the current benchmark ligand that displays many of the desirable qualities for industrial use. The improvement of radiolytic stability through ligand design is also discussed.1 Introduction and Background2 Dithiophosphinic Acids3 2,2': 6',2 ''-Terpyridine (TERPY) and Related Ligands4 2,4,6-Tri-2-pyridyl-1,3,5-triazine (TPTZ) and Related Ligands5 2,6-Bis(benzoxazol-2-yl)-4-dodecyloxypyridine (BODO) and Related Ligands6 Podand Ligands7 2,6-Bis(1,2,4-triazin-3-yl) pyridine (BTP) and Related Ligands8 6,6'-Bis(1,2,4-triazin-3-yl)-2,2'-bipyridine (BTBP) and Related Ligands9 Improving Radiolytic Stability through Ligand Design10 Conclusion and Outlook
