The preparation of some novel amidic extractants based on malonamides, glutaramides and succinamides and the vibrational spectroscopy of their complexes with thorium (IV), neodymium (III) and uranium (VI) is reported. These extractants have potential for use in nuclear fuels reprocessing plants. Vibrational spectroscopy shows the presence of nitrate groups in these metal complexes in monodentate or bidentate coordination. The succinamides and glutaramides were demonstrated to be equally successful in the formation and subsequent extraction of uranium (VI) complexes from aqueous nitric acid solutions and the malonamides were found to be less effective in accomplishing this. |
