摘　　要：使用Al2O3可以从硝酸铀酰的硝酸溶液[UO 2(NO3)2-HNO3]中同时提取MoO 24和IO 3。亚硫酸钠可以将IO3还原成I,利用Al2O3吸附IO3而不吸附I的性质,可将MoO42与IO3分离。使用2根Al2O3柱提取并分离UO2(NO3)2中MoO24和IO3后,Mo的平均回收率为78.3%±7.00%,钼产品中I的含量接近药典要求;I的平均回收率为87.9%±5.48%,碘产品中Mo的含量满足药用要求。实验结果表明,Al2O3可以用于医用同位素生产堆(MIPR)燃料溶液中的99Mo和131I的提取及分离。Alumina（Al2O3） can be used for the extraction of and from UO2（NO3）2 soluTion.can be reduced to by using Sodium sulphite,then and can be separated with Al2O3 for the unadsorption of on Al2O3.The total recovery yield of Mo and I is 78.3%±7.00% and 87.9%±5.48% respectively,after and in UO2（NO3）2 solution were separated with two Al2O3 columns,and Mo in iodide products solution and I in molybdenic products solution meet the requirements.The results indicate that Al2O3 can be used for 99Mo and 131I separation from the fuel of Medical Isotope Pro-duction Reactor.
