研究了CHON型萃取剂对镧系元素的萃取分离。CHON型萃取剂仅由C、H、O和N原子组成。N，N-二辛基二甘醇酰胺酸（DODGAA）对较重的镧系元素具有较好的萃取分离性能。另一方面，N，N，N '，N'-四（2-吡啶基甲基）乙二胺（TPEN）对较轻的镧系元素提供了前所未有的高选择性。此外，还发现DODGAA和TPEN在适当条件下的结合能够使轻、中、重镧系元素相互分离。
The extraction and separation of lanthanides have been investigated using CHON-type extractants, which are composed of only C, H, O, and N atoms. N,N-Dioctyldiglycol amic acid (DODGAA) showed high extraction and separation performances for heavier lanthanides compared with typical CHON-type extractants. On the other hand, N,N,N',N'-tetrakis(2-pyridylmethyl)ethylenediamine (TPEN) provided an unprecedentedly high selectivity for lighter lanthanides. Furthermore, it was found that the combination of DODGAA and TPEN under suitable conditions enabled the mutual separation of light, middle, and heavy lanthanides.
