摘要: 文中概述了铀中硼的分析方法 ,研究了阳离子交换色谱分离同位素稀释电感耦合等离子体质谱法 ( ID-ICP-MS)测量铀中硼的方法 ,对样品溶解方法、仪器参数、记忆效应、分离方法和洗脱液等进行了研究和优化选择。GBW0 4 2 0 4铀中硼标准物质的平均测量结果为 0 .5 4 μg/g U3O8,与参考值 0 .5 0 μg/g U3O8符合较好

Abstract: Separation and determination methods of trace boron in uranium were outlined. The method of determination of boron in uranium with ID-ICP-MS after cation ion-exchange separation was established. The dissolving methods of U 3O 8, the operating parameters of ICP-MS, the memory effects, the separation methods of boron in uranium and the washing solutions were studied and optimized. The concentration of boron measured in GBW 04204 was 0.54 μg/gU 3O 8, agreeable with the reference value of 0.50 μg/gU 3O 8.
