Solvent extraction of europium tri?uoromethanesulfonate into nitrobenzene in the presence of p-tert-butylcalix[6]arene and p-tert-butylcalix[8]arene
Original language description
From extraction experiments and gama-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-butyl-calix[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 25oC as log betanb(EuL3+) = 6.4 ? 0.1 (L = p-tert-butylcalix[6]arene) and log betanb(EuL3+) = 11.3 ? 0.1 (L= p-tert-butylcalix[8]arene).
