Mo在Al_2O_3上的吸附、解吸性能及其与U、Sr、Cs、I等杂质元素的分离

Adsorption and Desorption Properties of Mo on Al_2O_3 and Its Separation from U,Sr,Cs,I and Other Impurities

目前国际^(99)Mo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^(235)UO_2(NO_3)_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Al_2O_3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Al_2O_3从MIPR燃料溶液中提取^(99)Mo工艺可行。

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.
