Stability Constants of Ca2+, Cu2+, Zn2+, UO22+ , Mn2+, Co2+ and Ni2+ Complexes of Tetraethyl p-tert-Butylcalix[4]arene Tetraacetate in Nitrobenzene Saturated with Water

Original language description

From extraction experiments and y-activity measurements, the exchange extraction constants corresponding to the general equilibrium M2+ (aq) + SrL2+ (nb) - ML2+ (nb) + Sr2+ (aq) taking place in the two?phase water-nitrobenzene system (M2+ = Ca2+, Cu2+, Zn2+, UO22+ , Mn2+, Co2+, Ni2+; L = tetraethyl p-tert-butylcalix[4]arene tetraacetate; aq = aqueous phase, nb = nitrobenzene phase) were evaluated. Further, the stability constants of the ML2+ complexes in water saturated nitrobenzene were calculated; they were found to increase in the cation order Mn2+ - Co2+ - Cu2+ - Zn2+ - UO22+, Ni2+ - Ca2+.
