Mo在Al₂O₃上的吸附、解吸性能及其与U、Sr、Cs、I等杂质元素的分离

摘要: 目前国际⁹⁹Mo面临供应危机，急需新技术和新反应堆。医用同位素生产堆是以²³⁵UO₂(NO₃)₂溶液为燃料的专用反应堆，生产成本低、三废少、经济效益高。本工作利用Al₂O₃为分离材料，从模拟的医用同位素生产堆（MIPR）燃料溶液中分离和纯化Mo。结果表明，经两次分离，Mo的总回收率大于 60%， U、Sr、Cs、I等杂质可以被除去，采用Al₂O₃从MIPR燃料溶液中提取⁹⁹Mo工艺可行。

Abstract: The supply of ⁹⁹Mo will fall into crisis again and new technologies and new reactors for ⁹⁹Mo production are required. The medical isotope production reactor (MIPR) is a reactor with ²³⁵UO₂(NO₃)₂ solution as the fuel, which has the advantages of low cost, less waste and more economic benefits. Al₂O₃ was used as separation material to separate and purify Mo from the simulated MIPR fuel solution. The results showed that the total recovery of Mo can reach more than 60% after two column separation, and the impurities such as U, Sr, Cs and I can be effectively separated from Mo. Therefore, the production of ⁹⁹Mo from fuel solution of MIPR by using Al₂O₃ is feasible.
