| Popis: | This article presents novel techniques for characterising the kinetics of the free and bound water in a specimen by performing only one single sorption experiment. By monitoring the time-variation of the residual water in a specimen that undergoes a controlled non-isothermal sorption over the range of temperatures of interest, the initial mass of the free and bound water in the specimen, the Arrhenius constants of diffusivity of the free water and the Arrhenius constants of the rate of dissolution of the bound water can be extracted through a combination of time-temperature transformation and regression. |
