摘要: 研究了正丁基辛基亚砜(n-BOSO)、正戊基己基亚砜(n-PHSO)和乙基十二烷基亚砜(n-ED-SO)与1,10-双(1′-苯基-3′-甲基-5′-氧代吡唑-4-基)癸二酮-[1,10](H2A)对铀(Ⅵ)的协同萃取行为。用斜率法测得协萃合物的组成为UO2A·B(式中B分别代表n-BOSO、n-PHSO和n-EDSO),求得协萃平衡常数,用萃取法制得了固态协萃合物,并用元素分析、UV及IR光谱对其进行了表征。

Abstract: The synergistic extraction of uranium (Ⅵ) by 1,10-bis (1′-phenyl-3′-methyl-5′-oxopyra-zol-4′-y1)-1, 10-decanedione(H2A) and some asymmetric sulfoxides (n-butyloctyl-,n-pentylhexyl-,and ethyl-n-dodecyl sulfoxide,n-BOSO,n-PHSO, and n-EDSO, respectively) has been studied, By using slope analysis method the formula of the extraction complexes were shown to be UO2A·B(Brepresents sufoxide). The synergistic extraction eqilibrium constants were calculated. The solid extracted complexes have been characterized by elemental analyses, UV and IR spectroscopy.

Key words: bis-β-dione, asymmetric sulfoxide, uranium(Ⅵ), synergistic extraction
