本文叙述了在 P_(204)萃淋树脂床上用无机酸淋洗分离 Tm~(+3)—Yb~(+3) UO_2~(+2)—Th~(+4)、UO—Fe~(+3)及 UO_2~(+2)—Eu~(+3)—Yb~(+3)—Ce~(+3)的实验结果;测定了用4NHNO_3淋洗分离 Tm~(+3)—Yb~(+3)时的分离因数;并对 UO_2~(+2)在固、液两相间的分配进行了研究.
This paper describes the separation of Tm ~ (+3) -Yb ~ (+3) UO_2 ~ (+2) -Th ~ (+4) and UO-Fe ~ +3) and UO_2 ~ (+2) -Eu ~ (+3) -Yb ~ (+3) -Ce ~ (+3). The results showed that Tm ~ (+3) -Yb ~ (+3). The distribution of UO_2 ~ (+2) in solid and liquid phases was also studied.
