General relations among thermodynamic parameters, which characterize the transfer of the ions H+ and OH- from the aqueous into nitrobenzene phase of the two-phase water-nitrobenzene extraction system and dissociation equilibria of H2O in both phases of this system, have been derived.

From extraction experiments and γ-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+, K+, Rb+, Cs+; L = benzo-18-crown-6; aq = aqueous phase, nb = nitrobenzene phase) were evaluated.

Abstract The facilitated transfer of the Na + cation through the water (w)/nitrobenzene (nb) interface affected by dibenzo-18-crown-6 dissolved in the organic phase was studied by the cyclic voltammetry in the temperature range of 5–65°C. The transfer was found to be a very fast process at each studied temperature (5, 20, 35, 50, and 65°C); the ...

Abstract By using known thermodynamic parameters, the Briggs logarithms of the individual extraction constants for the ML + complex cations (M + = Na + , K + , Rb + , Cs + ; L = dibenzo-24-crown-8) in the water—nitrobenzene extraction system at 25 C have been evaluated. It has been found that these constants increase in the order Na + + + + ,

Standard Gibbs energies of transfer of cesium ion from water to nitrobenzene and nitrobenzene-carbon tetrachloride mixture have been evaluated from electrochemical measurements. From the results the conclusion can be drawn that with increasing dielectric permitivity of organic mixed solvents the value of the Gibbs transfer energy of Cs+ ion decreases.
