    Diffusion in the system water + tri-n-butyl phosphate. Effect of aqueous electrolytes, and of organic phase water concentration
    (Journal of the Chemical Society : Faraday Transaction - I. The Chemical Society, London. 1974, 70 (1-6), 1974) Hipfner, Jerold C.; Tuck, Dennis G.
    The interfacial permeability coefficient k for the transfer of water across the water/tri-n-butyl phosphate (TBP) interface has been determined as a function both of aqueous electrolyte concentration, and of the initial water concentration in the TBP. The diffusion coefficient D of water in the organic phase has also been measured. Both k and D are found to be independent of electrolyte concentration over the range 0–1 mol dm–3 aqueous NaCl, and for 1.25 mol dm–3 aqueous Cr(NO3)3. The coefficient D is dependent on the initial water concentration in the TBP phase, with a maximum value at a TBP/H2O mole ratio ≈2. The results are discussed in terms of possible diffusion mechanisms.
