dc.description.resumen | En este trabajo se realizó una caracterización superficial del sistema Metanol-agua a 293.15K y Etanol-agua a 298.15 K usando un modelo desarrollado para este propósito. La implementación del modelo se logró a partir de datos de tensión superficial (σ), densidades (ρ), volúmenes críticos (m_(ic,s)), coeficientes de actividad a dilución infinita 〖(γ〗_i^∞) y áreas molares superficiales (A_i) reportados en literatura. Como resultado de la implementación se obtuvieron: concentraciones superficiales (_i), fracciones molares superficiales (x_1^s) y moles superficiales (n_i^s) respecto a cada uno de los sistemas. Estos resultados fueron comparados con otros artículos previamente publicados. Observándose una buena concordancia. | |
