研究了高放废液中金属元素在 PAIV(酰胺荚醚 )萃淋树脂色层柱上的吸附及淋洗性能。选择合适的淋洗条件 ,能使微量钕和大量杂质元素分离 ,用 ICP- MS法测定钕含量 ,扣除空白 ,钕回收率为 96.8%～ 1 0 6%。
The adsorption and elution properties of metal elements in PAW (amide-pod ether) chromatography resin column were studied. Choosing suitable conditions of leaching can separate trace amounts of neodymium and a large amount of impurity elements. The neodymium content was determined by ICP-MS method. The blank recovery was 96.8% ~ 106% after deducting the blank.
