| 英文摘要 | The extraction of Nd3+ and Sm3+ including the extraction and stripping capability as well as the separation effect of Nd3+ or Sm3+, from a sulfuric acid medium, by mixtures of di-(2-ethylhexyl) phosphoric acid (HDEHP, H(2)A(2(0))) and 2-ethylhexyl phosphoric acid mono-2-ethylhexyl ester (HEH/EHP, H2L2(0)) were studied. The distribution ratios and synergistic coefficients of Nd3+ and Sm3+ in different acidities were also determined. A synergistic extractive effect was found when HDEHP and HEH/EHP were used as mixed extractants for Sm3+ or Nd3+. The chemical compositions of the extracted complex were determined as Nd center dot(HA(2))(2)center dot HL2 and Sm center dot(HA(2))(2)center dot HL2. The extraction equilibrium constants, enthalpy change, and entropy change of the extraction reaction were also determined. |
