LnやAn相互分離は原子力分野のみならず、一般の産業界でも注目される。ネオジム磁石からDyの分離は耐熱性向上の観点から、またAm/Cm分離は発熱性や中性子放出核種の分離の観点から分離が求められる。DGA系溶媒抽出を用いて多段抽出による相互分離の結果について述べる。

The separation of Lanthanides and actinides is noticed for not only atomic energy field but also general industry. These separation methods are requested on the points of Dy from Nd magnet and reductant of heat source and neutron emitter of Cm from Am. In the presentation, the results of separation of Dy and Nd by counter-current multi-step extraction will be mentioned.
