Abstract
The group contribution approach is a reliable and fast method for the prediction of liquid phase activity coefficients in none lectrolyte, nonpolymeric mixtures at low to moderate pressures and temperatures between 300 and 425 K. It has become widely used in practical chemical engineering applications in cases where little or no relevant experimental information is available.
The two group contribution methods examined in the course of this work, are the Knox and & UNIFAC models. Group interaction parameters are evaluated for each of these models and results compared. Although the results for both models are similar when sufficient data are available, the Knox model gives consistently better results with less data. ( Reference 12).
Also studied during the course of this work was the Toxicity Characteristic Leaching Procedure, an EPA approved procedure for testing the Leaching Characteristics of contaminated soil.
