摘要:
在研究 HCl 体系中 Er( III ) Tm( III ) Yb( III ) Lu( III ) 离子在瑞萃淋树脂淋洗行为的基础上 , 发现 Er Tm Yb Lu 各元素的分配系数 kd 随酸度增高而递减 在色谱柱的淋洗过程中 , 按原子序数从小到大顺序被洗脱 . 1.0~4.0mol/ L HCI 进行阶梯淋洗 , 进料量 1.0% ~1.5% 均能达到基线分离 . 在色谱柱床中 ,RE 3+ 离子与 P507 发生化学反应 , 生成的化合物可认为是 REA3 ..
Abstract:
The levextrel behavior of Er(III) ,Tm(III) ,Yb(III )and Lu(III) in HC1 solution has been studied using a chromatographic column with P507 levextrel resin. It is found that the distribution coefficient (kd)of Er, Tm, Yb and Lu decreases with the decrease in the acidity and the adjacent element separation coefficient, respectively, and that the ions are eluted in the order of the atomic number and the baseline separation is achieved through the eluent of 1.0~4.0 mol/L HC1 and the feed proportion of 1.0% ~1.5%. Moreover, the product due to the reaction of RE3+ to P507 can be considered as REA3 .
