| 摘要: 本文研究了1,10-双(1'-苯基-3'-甲基-5'-氧代吡唑-4'-基)癸二酮-[1,10](H2A)与1,10-菲罗啉(phen)或2,2'-联吡啶(dipy)对Co(Ⅱ)的协同萃取行为。确定了协萃配合物的组成为CoA·B(B分别为Phen和dipy),求得萃取平衡常数logKex分别是4.78(H2A+phen)和1.61(H2A+dipy),并对协萃配合物的IR谱进行了讨论。 |

| Abstract: With the 1,10-bis(1'-phenyl-3'-methyland 1,10-phenanthroline(phen) or 2,2'-bipyridyl (dipy),the synetgistic extraction behaviors ofco(Ⅱ) have been investigated.The synergistic extracted complexes have been shown to be CoA·phen and CoA·dipy respectively.The values.of the extraction equilibrium constantsshow large synergistic effect.The solid synergistic extrated complexes were prepared and its IRhas been discussed. |
