Abstract
From extraction experiments and γ-activity measurements, the extraction constants corresponding to the general equilibrium Eu3+(aq) + 3A−(aq) + L(nb) ⇔ EuL3+(nb) + 3A−(nb) taking part in the two-phase water–nitrobenzene system (A− = CF3SO3 −; L = p-tert-butylcalix[6]arene, p-tert-butylcalix[8]arene; aq = aqueous phase, nb = nitrobenzene phase) were evaluated. Further, the stability constants of the EuL3+ complexes in nitrobenzene saturated with water were calculated for a temperature of 25 °C as log β nb(EuL3+) = 6.4 ± 0.1 (L = p-tert-butylcalix[6]arene) and log β nb(EuL3+) = 11.3 ± 0.1 (L = p-tert-butylcalix[8]arene).
