摘要：
Extraction of HNO3 and microamounts of Am and Eu from nitric acid solutions with solutions of bidentate butyl (phosphorylmethyl) phenylphosphinates R2P(O)CH2P(O)Ph(OBu) [R = octyl (I), phenyl (II), p-tolyl (III), p-anisyl (IV)] in 1,2-dichloroethane was studied. The stoichiometry of the extractable complexes was determined, and the apparent extraction constants were calculated. The extractive power of the reagents studied toward HNO3 increases in the order II < III < IV < I, and toward Am(III), in the order I < II < III < IV.
