Abstract
El equilibrio de sorción de agua a diferentes temperaturas (25, 35, 50 y 60°C) en un rango de humedad relativa, de 0.10 a 0.85, se determinó para la uchuva usando un método gravimétrico estático. El calor isostérico y la energía libre de Gibbs se calcularon desde el equilibrio de sorción. Los modelos de GAB, BET, SMITH, el modificado de Halsey, el modificado Chung-Pfost, el modificado de Oswin y el modificado de Henderson fueron probados para ajustar los datos experimentales. El modelo GAB fue el más adecuado para describir las curvas de sorción. Los valores de contenido de humedad de la monocapa para la sorción a diferentes temperaturas fueron calculados usando...
