چکیده:

In this study, the Langmuir adsorption isotherm coupled with the Meissner and extended UNIQUAC activity coefficient model have been used for prediction of surface tension of mixed electrolyte solutions. Using single electrolyte experimental data, the model parameters were determined through minimizing the absolute average relative deviation. Then the surface tension of mixed electrolyte solutions were predicted. The results show that the extended UNIQUAC model can be used for prediction of surface tension in mixed electrolyte solution efficiently.
