Solvent extraction behaviors of Am(III) and Eu(III) using 2-hydroxy-2-methyloctanoic acid (Hhmo) and 2-hydroxy-2-trifluoromethyloctanoic acid (Hhfo) were investigated in aqueous acetic acid/1-octanol at 20 °C. In both cases, distribution ratios (D) of the organic/aqueous phases increased with increasing pH of the aqueous solution. The D Am(Hhfo) and D Eu(Hhfo) values were found to be much higher than those for D Am(Hhmo) and D Eu(Hhmo), respectively, under similar pH conditions. The maximum separation factor of D Eu(Hhfo)/D Am(Hhfo) was 2.31 ± 0.800.70 at pH 4.29. The differences between D Am(Hhmo) and D Eu(Hhmo) values were relatively small in the pH region under consideration.
