Description

From extraction experiments and activity measurements, the exchange extraction constants corresponding to the general equilibrium M+(aq)+NaL+(nb)↔ML+(nb)+Na+(aq) taking place in the two-phase water-nitrobenzene system (M+ = Li+, H3O+, NH4+, Ag+; L = hexaethyl calix[6]arene hexaacetate; aq = aqueous phase, nb = nitrobenzene phase) were determined. Furthermore, the stability constants of the ML+ complexes in water saturated nitrobenzene were calculated; they were found to increase in the cation order H3O+<NH4+<Li+<Ag+. (author)
