A mathematical model aimed to predict the hexanal sorption kinetic into an aldehyde scavenger film is presented. The proposed model is based on the assumption that the sorbed hexanal molecules are in part randomly dispersed into the polymeric matrix and in part chemically bonded to the polymeric matrix. To validate the model hexanal sorption kinetics were determined at 25°C and at 3 different hexanal activity. The proposed model satisfactorily fits the experimental data suggesting that hexanal absorption by the active film is a complex phenomenon involving both chemical reaction and physical reversible absorption

Abstract
A mathematical model aimed to predict the hexanal sorption kinetic into an aldehyde scavenger film is presented. The proposed model is based on the assumption that the sorbed hexanal molecules are in part randomly dispersed into the polymeric matrix and in part chemically bonded to the polymeric matrix. To validate the model hexanal sorption kinetics were determined at 25°C and at 3 different hexanal activity. The proposed model satisfactorily fits the experimental data suggesting that hexanal absorption by the active film is a complex phenomenon involving both chemical reaction and physical reversible absorption
