Abstract:
Activity coefficients and Henry's law constants for 25 organic priority pollutants were estimated using UNIFAC thermodynamic calculations. For 6 of these compounds, the results were compared with measured values reported in the literature. This indicated errors in the UNIFAC predictions varying from 24.0% to 95.0%. Best results with UNIFAC were obtained using liquid-liquid equilibria, rather than vapor-liquid equilibria.
Octanol/water partition coefficients were also estimated for the same 25 organic priority pollutants using the fragment constant method. Results differed from values reported in the literature by 5% to 170%.
Estimated activity coefficients were also used to predict stripping rates of organic priority pollutants from aerated batch and continuous flow reactors.
