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 298.15 K 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.
