摘　　要：研究了水合二氧化锰(HMD)和水合五氧化二锑(HAP)对铀的吸附性能,以及在HNO3溶液中对Sr、Cs、Zr、Ru、Se、Ce和Sm的吸附性能。HMD和HAP在硝酸铀酰溶液中不吸附铀。HMD在0.2 mol/LHNO3溶液中对Zr、Ru和Se的吸附性能较好,HAP在0.2 mol/L HNO3溶液中对Sr、Cs、Ce和Sm的吸附性能较好。含有Sr、Sm、Ru、Ce、Zr和Se混合元素的0.2 mol/L HNO3依次通过HMD和HAP柱吸附后,元素基本被全部吸附。研究结果表明,HMD和HAP可以用于HNO3溶液中Sr、Sm、Ru、Ce、Zr、Cs和Se等医用同位素生产堆燃料溶液中主要裂变产物元素的去除。The adsorption behavior of U, Sr, Cs, Zr, Ru, Se, Ce and Sm on hydrated manganese dioxide （HMD） and hydrated antimony pentoxide （HAP） was studied. HMD and HAP have no adsorbability for uranium. Zr, Ru and Se are strongly adsorbed by HMD, while Ce, Sr, Sm and Ce are strongly adsorbed by HAP. Sr, Zr, Ru, Se, Ce and Sm in nitric acid solution can quantitatively be absorbed on the exchangers, by passing the solution successively through a HMD column and a HAP column. The results show that HMD and HAP can be used for the removal of fission products such as Sr, Cs, Zr, Ru, Se, Ce and Sm in the fuel solution from medical isotope production reactor（MIPR）.
