AB  - The mutual separation of lanthanides has been studied by multi-stage extraction 
      using an extractant, DGA (diglycolamide) compounds. N,N,N',N'-tetraoctyl-DGA 
      (TODGA) has a high extractability to lanthanides and a relatively high separation 
      factor (SF) between Dy and Nd (SF of over 20) from HNO(3) media. Complete 
      separation with such SF values can be achieved by multi-stage extraction. Less 
      information on multi-stage extraction compared to batch extraction has been 
      presented up to now. We thus conducted a basic study. By confirming the 
      experimental data to be identical to calculations, the sample solution including 
      both metals was employed for batchwise multi-stage extraction. Ninety-seven 
      percent of Dy with under detection limit of Nd could be recovered into the 
      organic phase from Nd with a ten-times higher concentration than Dy using the 
      condition, 0.1 M TODGA/n-dodecane and 0.3 M HNO(3) by the multi extraction of 9 x 
      9 stages for organic and aqueous phases.
