Abstract
The influence of the concentration of dimethylaminomethylated calix[4]resorcinolarene I, pH, supporting electrolyte, and additions of 1,10-phenanthroline to the organic phase on the distribution of Eu(III) and Am(III) between the aqueous and organic phases was studied. Compound I extracts Am and Eu ions from neutral aqueous solutions more efficiently when dissolved in 1-heptanol, compared to dichloroethane. Extraction is accompanied by formation of the third phase containing large amounts of the metals. As the concentrations of I and supporting electrolyte are increased, the Am/Eu separation factor grows, but in this case noticeable amounts of the metals appear in the third phase, which restricts the applicability of this system. Additions of 1,10-phenanthroline to the organic phase decrease by 2-3 orders of magnitude the concentration of I required for efficient extraction of Am and Eu, showing a synergistic effect.
