WebMar 31, 2005 · The parameters in the GAB sorption isotherm support the theory of localised sorption, establishing the existence of different classes of water. Moreover, the …
WebFor the GAB model, F(GAB) and RH have a linear relationship once k is determined. Hence, a series of k values with an interval of 0.01 is used to conduct the linear regression (the fitting process of the BET model), and then the group with the best linearity is used as the final fitting result. Once the input isotherm data are determined, the ... WebFeb 22, 2024 · The GAB model is an extension of the BET model, taking into consideration the modified properties of the sorbing materials in the multilayer region and the bulk liquid properties through the introduction …
WebThe Guggenheim–Anderson–de Boer (GAB) model can be used to describe how foods and other materials absorb and desorb moisture and how this affects Aw. The GAB model gives similar results in many instances to the Brunauer-Emmett-Tellet (BET) model and is equivalent to the BET model when K=1. WebJun 28, 2008 · The most extended model used to describe the sorption isotherms is the Guggenheim, Anderson and de Boer (GAB) isotherm equation as it has shown a good fitting up to water activity values of 0.9...
