摘要：

Extraction behavior of Am3+ with six kinds of crown ethers(CE) and 2-thenoyltrifluoroacetone(HTTA) in benzene, cyclohexane and 1,2-dichloroethane was studied. Synergistic extraction of Am(TTA)(3)(CE) was observed using benzene and cyclohexane and adduct formation constants were determined. We found the steric effect of CE is important as well as basicity of CE for the evaluation of the adduct formation constants. Ion-pair extraction of Am(TTA)(2)(CE)(n)(+) was observed with 1,2-dichloroethane.
