本工作是用~(150)Nd及~(154)Sm作同位素稀释剂,将Nd,Sm从核燃料溶解液中(~(235)U丰度10%)分离出来,用同位素稀释质谱法测燃耗。Nd,Sm的分离方法,首先是用两根HDEHP萃淋树脂柱预处理纯化稀土。调节溶
In this work, isotope dilution of ~ (150) Nd and ~ (154) Sm was used to separate Nd and Sm from nuclear fuel solution (~ (235) U abundance of 10%) and isotope dilution mass spectrometry Consumption Nd, Sm separation method, the first is to use two HDEHP extraction resin column pretreatment of purified rare earth. Adjust the solution
