Radiolysis of water-nitrobenzene-carbon tetrachloride and water-chlorobenzene-carbon tetrachloride two-phase systems. Radiation yields of chloride ions

Journal of Radioanalytical and Nuclear Chemistry Letters, 1992
The influence of nitrobenzene and chlorobenzene on the total radiation yield of chloride ions in the γ-irradiation of water-carbon tetrachloride two-phase systems has been determined. Nitrobenzene at small concentrations shows a pronounced protective influence on the radiation destruction of carbon tetrachloride.

Transfer of cesium ion from the aqueous phase into the mixed organic phase of a two-phase water/nitrobenzene-carbon tetrachloride extraction system

Journal of Radioanalytical and Nuclear Chemistry Articles, 1991
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.

Chemical equilibria including particles I-, I3-, I5-, and I2 in two-phase water-nitrobenzene extraction system

Collection of Czechoslovak Chemical Communications, 1990
General relations among thermodynamic parameters characterizing chemical equilibria with species I-, I3-, I5-, and I2 in the two-phase water-nitrobenzene extraction system have been derived. Furthermore, these relations have been used for calculating equilibrium constants K1aq(I3-) and K2aq(I5-) corresponding to homogeneous reactions I-(aq) + I2(aq ...

Thermodynamic parameters characterizing complexes of alkali metal cations with dibenzo-24-crown-8 in the water—nitrobenzene extraction system

Colloids and Surfaces, 1992
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 + + + + ,
