A monoamide, N,Nâ²-dioctyl, α-hydroxy acetamide, shows unusual extraction properties towards trivalent lanthanide and actinide ions above 3 M HNO3. The extracted ions could be quantitatively back extracted using 0.5 M HNO3. This amide shows negligible extraction towards Sr(II) and Ru(III) ions, making it advantageous over other reported extractants. The structures of Sm(III) and Eu(III) nitrate compounds show that the metal ion is surrounded by three of the ligands, one nitrate and one water molecule. The ligand acts as a neutral bidentate ligand and bonds through the amido and hydroxyl oxygen atoms.
一种名为 N,Nâ²-二辛基δ-羟基乙酰胺的单酰胺对三价镧系元素和锕系元素离子具有不同寻常的萃取特性,萃取浓度高于 3 M HNO3。被萃取的离子可以用 0.5 M HNO3 进行定量反萃取。这种酰胺对 Sr(II) 和 Ru(III) 离子的萃取作用可以忽略不计,因此与其他已报道的萃取剂相比更具优势。Sm(III) 和 Eu(III) 硝酸盐化合物的结构显示,金属离子被三个配体、一个硝酸盐和一个水分子包围。配体为中性双齿配体,通过氨基和羟基氧原子结合。
