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](H_2A)对铀(Ⅵ)的协同萃取行为。用斜率法测得协萃合物的组成为UO_2A·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。
The synergistic extraction of uranium (Ⅵ) by 1,10-bis (1'-phenyl-3'-methyl-5'-oxopyra-zol-4'-y1)-1, 10-decanedione(H_2A) 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 UO_2A·B(Brepresents sufoxide). The synergistic extraction eqilibrium constants were calculated. The solid extracted complexes have been characterized by elemental analyses, UV and IR spectroscopy.
