英文摘要 | In recent years, there has been a trend to use synergistic systems of neutral and acidic extractants into a single-solvent formulation to achieve ln(3+)/an(3+) extraction and separation via simplified processing schemes. in this study, geometrical structures, bonding nature, and thermodynamic stabilities of a series of possible extraction complexes of am3+ and eu3+ with two neutral-acid synergistic systems (cmpo-hdehp and cmpo-heh[ehp]) were theoretically studied using scalar-relativistic density functional theory (dft). it is found that hydrogen bonds between neutral and acid ligands may greatly influence the eu3+/am3+ extraction and separation performance of the two synergistic systems. according to natural bond orbital (nbo) and energy decomposition analyses (eda), the phosphoryl oxygen atoms of hdehp or heh[ehp] have higher affinity for eu3+ and am3+ than those of the cmpo ligand. since weak but different extents of covalency exist in eu- and am-complexes, eu3+/am3+ separation via these two systems may be attributed to the different compositions of interactions between the metal ions and ligands. thermodynamic analysis shows that the neutral complexes ml(no3)(2) (m = eu and am; l = [cmpo-dehp](-) and [cmpo-eh[ehp]](-)) appear to be the most probable species in the complexation process. |
