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.
- bis-β-dione,
- asymmetric sulfoxide,
