"From extraction experiments and c-activity measurements, the extraction constants corresponding to the general equilibrium Eu(3+)(aq) + 3A(-)(aq) + L(nb) <-> EuL(3+)(nb) ? 3A(-)(nb) taking part in the two-phase waternitrobenzene system (A(-) = CF(3)SO(3)(-); L = p-tert-butylcalix[6] arene, p-tert-butylcalix[8] arene; aq = aqueous phase, nb = nitrobenzene phase) were evaluated.
