研究了由Np 到Lr 超铀元素分析化学的现状。给出了重要同位素的基本特性数据,讨论了金属和氧化物的性质。特别注意了溶液中非一般氧化态超Pu 元素的性质变化、制备方法、稳定程度以及这些元素的现代分离方法。最后讨论了超铀元素和其中杂质的主要测定方法。引言近年来,超铀元素的研究在世界上很多国家迅速发展。这是由于这些元素具有大的科学价值,它们的化学、物理性质研究得还 The status of the analytical chemistry of transuranics from Np to Lr was studied. The basic properties of important isotopes are given, and the properties of metals and oxides are discussed. Particular attention is paid to the change in properties of the non-generalized ultra-Pu element in solution, the preparation method, the degree of stabilization, and the modern separation of these elements. Finally, the main methods of determination of transuranics and impurities therein are discussed. Introduction In recent years, the research on transuranic elements has been rapidly developed in many countries in the world. This is because these elements have great scientific value, and their chemical and physical properties have also been studied
