Abstract

Our earlier reported work for densities of mixed aqueous solutions was extended for the prediction of density of mixed organic solutions containing tri-n-butyl phosphate, diluent and solvates of the electrolytes-UO2(NO3)2 and HNO3. Two empirical equations for density of mixed organic solutions have been reported. The first equation predicts density at 298.15K while the other equation predicts temperature dependency of density in the range of 283.15K to 333.15K. A novel feature of this model is consideration of TBP as a solute, rendering equations valid over the full range of TBP concentrations. Good agreement was observed between the published experimental data and predicted values from model reported in this work.
