摘要介绍了水相中重元素快速化学分离的实验技术。通常,这些包括通过气体喷射技术将核反应产物输送到分离装置和溶解在含有无机配体的水溶液中以形成络合物。配合物的化学特征在于分配方法,可以是液-液萃取,离子交换或反相萃取色谱。将分离的馏分快速蒸发至干,用于制备α粒子光谱学样品。对化学研究中必须用单原子的特殊情况作了评述。化学性质的理论预测进行比较,目前已知的化学行为的rutherfordium,Rf(元素104),dubalgium,Db(元素105),seaborgium,Sg(元素106),和hexalgium,Hs(元素108)和它们的轻同系物在周期表中,以评估相对论效应的作用,在化学中的最重的元素。
Abstract The experimental techniques developed to perform rapid chemical separations of the heaviest elements in the aqueous phase are presented. In general, these include transport of the nuclear reaction products to a separation device by the gas-jet technique and dissolution in an aqueous solution containing inorganic ligands for complex formation. The complexes are chemically characterized by a partition method which can be liquid–liquid extraction, ion-exchange- or reversed-phase extraction chromatography. The separated fractions are quickly evaporated to dryness for the preparation of samples for α-particle spectroscopy. Comments are given on the special situation in which chemistry has to be studied with single atoms. Theoretical predictions of chemical properties are compared to the presently known chemical behaviour of rutherfordium, Rf (element 104), dubnium, Db (element 105), seaborgium, Sg (element 106), and hassium, Hs (element 108) and to that of their lighter homologs in the Periodic Table in order to assess the role of relativistic effects in the chemistry of the heaviest elements.
