The thermodynamic model of the extraction of W with primary amine under near neutral conditions is reported in this paper. The activity coefficients of the nonelectrolytes in organic phase are calculated by the Margules and NRTL equations which are based on previously tested liquid-liquid extraction equilibrium data in combination with mass balances ...

Journal of Chemical & Engineering Data, 2012
This article deals with the mean activity coefficients of RbF or CsF in the glycine + water mixed systems. The Pitzer, the modified Pitzer, and the extended Debye–Huckel equations are used to describe the nonideal behavior of the electrolyte. The osmotic coefficients, the excess Gibbs free energy, and the standard Gibbs energies of transfer were ...

Fluid Phase Equilibria, 1992
Abstract Lu, J.-F., Niu, S.-F. and Li, Y.-G., 1992. Study on the salting effect of di(2-ethylhexyl) phosphoric acid in MCl2(MSO4) solutions by Pitzer-Li and Pitzer equations. Fluid Phase Equilibria, 71: 211-224. The radioisotope (32P) technique is used to measure the solubility of di(2-ethylhexyl) phosphoric acid (D2EHPA) in MCl2 and MSO4 solutions.

Plutonium disproportionation: Pitzer parameters or precipitates?
Journal of Radioanalytical and Nuclear Chemistry, 2004The behavior of dissolved pentavalent plutonium in the presence of hydrous plutonium oxides has recently been described in terms of Pitzer parameters. The observations can be explained by a conventional approach. The alternative perspective does not use the irreversible oxygen/water couple and it is easier to understand than virial expansions and ...

Extension of the pitzer correlation for compressibility factor calculations
The Canadian Journal of Chemical Engineering, 1979AbstractThe three‐parameter generalized correlation of Pitzer et al (1955) for calculating the compressibility factor Z of normal fluids in the Tr and Pr regions of 0.8 ≦ Tr ≦ 4.0 and 0 ≦ Pr ≦ 9.0 has been extended to wider ranges, using the P‐V‐T data available in the literature for 53 compounds with a total number of data points about 15,000.
