2,2'-(Methylimino)bis(
N,
N-di-
n-octylacetamide) (MIDOA or MIDAA) is a new efficient metal extractant, developed by Sasaki
et al.1) MIDOA is highly lipophilic and ready to use in the HNO
3(aq.)–
n-dodecane extraction system. MIDOA has high extractability for metal ions classified soft acids because of the nitrogen donor atom centered in the backbones, complementary of hard ions extractant TODGA
[O0523]. Therefore, the distribution ratio for Tc(VII) is extremely high. In addition, Cr(VI), Re(VII), Mo(VI), W(VI), Pd(II) and Pu(IV) are well extracted by MIDOA.
