| 摘要: 本文研究磷酸三丁酯(TBP)与二苯基亚砜(DPSO)组成的二元中性体系(B-B体系)在HCl介质中对金(Ⅲ)的萃取行为,发现该体系有明显的协同萃取效应.用斜率法和紫外光谱法确定了协萃配合物的组成为H3O+·2TBP·DPSO·yH2O……AuCl4-·HCl.协萃反应的平衡常数log K1,2′=3.33.对协萃反应的机理和可能的结构也进行了讨论. |

| Abstract: The synergic extraction of gold(Ⅲ)from hydrochloric acid medium with mixtures of tributyl phosphate(TBP)and diphenyl sulfoxide(DPSO)in benzene has been investigated.The formation of the extracted species H3O+·2TBP·DPSO·yH2O…AuCl4-·HCl is confirmed by slope analysis and UV spectra. The equilibrium constant of the extraction reaction log K1,2′=3.33 is calculated. |
