| 摘要: 考察了低酸度下二(2—乙基己基)亚砜(DEHSO)萃取钯(Ⅱ)的机理.研究了H+、Cl-和温度对分配比的影响.萃取剂浓度较高时([DEHSO](o):[Pd2+]>2:1)反应为 Pd2++2Cl-+2DEHSO(o)⇔[PdCl2(DEHSO)2](o) 萃取剂浓度较低时,反应为 2Pd2++4Cl-+2DEHSO(o)⇔[PdCl2(DEHSO)2](o) 用斜率法、Asmus法、饱和法、固态萃合物的组成分析及红外图谱确定了萃合物的组成和结构. |

| Abstract: In this paper, we have studied the behaviour of extraction of pal-ladium(I)by Di-(2-ethylhexyl)sulfoxide(DEHSO)at low acidity medium. The effects of [H+], [Cl-] and temperature on the distribution ratio have been investigated. When the concentration of the extractant is higher([DEHSO](0):[Pd2+]>2:l), the reaction is Pd2++2Cl-+2DEHSO(o)⇔[PdCl2(DEHSO)2](o) When the concentration of the extractant is lower, the reaction is 2Pd2+4Cl-+2DEHSO(o)⇔[PdCl2(DEHSO)2](o) The composition and structure of the extracted complex are comfirm-ed by slope method, Asmus's method, saturation method, elementary analysis and infrared spectrum. |
