摘要：

Four asynchronous experiments were performed for a total of twelve samples, to characterize the pulp adsorption with basic groups at its surface. Three asynchronous experiments were performed for a total of nine samples, to characterize the pulp adsorption with acidic groups at its surface. The mass of water adsorbed per unit mass of dry pulp was plotted as a function of time. The results confirm that the kinetics of humidity adsorption for the first regime can be described as typical of a first order process.
