摘要
中国原子能科学研究院(简称原子能院)利用电磁法完成了国家科技支撑计划课题《科研用高纯有机试剂核心单元物质及共性关键技术的研制与开发》,利用电磁法有效分离了54 Fe、65 Cu、64 Zn、67 Zn、207 Pb以及85 Rb、87 Rb同位素制剂,其丰度分别达到:90%、99.6%、96%、81%、90%、99%、98%。其中部分同位素试剂达到国外产品标准,部分已经应用在我国科研生产及全球卫星导航定位系统中。
China Institute of Atomic Energy(CIAE) has accomplished state science and technology support plan topic(( research and development of high purity organic reagent corn unit using for research and commonness key technology)). S4Fe,65 Cu.64 Zn,67 Zn207 Pb and 85Rb.87 Rb were separated using electromagnetic method. And the abundances of them ar chived: 90%, 99.6%, 96%, 81%, 90%, 99% and 98%. The level of these isotopes prepa ration has reached overseas product standard. Some of them have been used in the production of science research and rubidium clock production for satellite navigation. It established / technology base for material domestic production of special stable isotopes in China.
