Ion-exchange behavior of element 104, Rf, in HCl and HNO_3 solutions

本工作的目的是阐明元素周期表第7周期104号元素Rf的离子交换性质。在这项工作中，我们研究了锆和铪，同系物Rf，在盐酸和硝酸溶液中使用TB P，TIOA，和Aliquat 336树脂的离子交换行为。在此基础上，确定了Rf实验的实验条件，并与Rf实验进行了对比，讨论了Rf的离子交换性能。此外，我们还研制了一种快速离子交换装置，它可以通过气体喷射输送系统与加速器相连，用于核反应产物的输送。通过使用加速器实际进行在线离子交换实验来检查装置的性能。

Purpose of the present work is to clarify the ion-exchange properties of element 104, Rf, which lies at the 7th period in the periodic table. In this work, we investigated the ion-exchange behaviors of Zr and Hf, homologues of Rf, in HCl and HNO3solutions using TB P, TIOA, and Aliquat 336 resins. From these results, we determined the experimental conditions of Rf experiment and obtained the comparative data with those of Rf to discuss the ion-exchange properties of Rf. In addition, we also developed a rapid ion-exchange apparatus which can be connected with an accelerator through a gas-jet transportation system for nuclear reaction products. Performance of the apparatus was checked by actually conducting an online ion-exchange experiment using an accelerator.
