摘　　要：本文测定了不同条件下钆和铕的分离因数。结果表明,当只有EDTA存在时,钆和铕的分离因数为1.30,而当加入适量的弱酸盐乙酸铵后,它们的分离因数可增大到1.51。另外,温度对钆、铕的分离因数没有明显的影响。In this paper, the Eu - Gd separation factors have been determined in different conditions. It is shown that only in the presence of EDTA,the Eu-Gd separation factor is 1. 30, and in the presence of EDTA and NH4Ac, the separation factor is 1. 51. In addition, the variations of temperature doesn't affect the separation factor.
