- Highly selective extraction of TcO4-, ReO 4-, and MoO42- by the new ligand, 2,2′-(methylimino)bis(N,N-dioctylacetamide) (MIDOA)
-
Highly selective extraction of oxonium anions can be achieved by the new ligand, 2,2′-(methylimino)bis(N,N-dioctylacetamide) (MIDOA). MIDOA has a high solubility in n-dodecane, any types of diluents can be employed for the solvent extraction. The extraction using MIDOA was performed under the condition, HNO3 and n-dodecane, considering the chemical process of high-level radioactive liquid waste. It was obvious that the oxonium anions, like TcO4-, ReO4_, Cr 2O72-, MoO42-, and WO42-, are extracted, and the distribution ratios (D) decrease with increase of HNO3 concentration. Copyright

- Method for extraction of metals by methyliminobisalkylacetamide
-
The present invention provides a method for extraction of metals selected from Cr, Mo, Pd, Tc, W, Re, and Pu using a new extractant of methyliminobisalkylacetamide represented by a formula (I): [in-line-formulae]CH3—N—(CH2CONR2)2??(I)[/in-line-formulae] wherein R represents an alkyl group having 8-12 carbon atoms.
