Vapour Sorption Studies of Belmadur Wood

In this study, the water vapour sorption of Belmadur wood is fully investigated. The sorption isotherms were analysed using the Hailwood-Horrobin model. Belmadur wood was shown lower total sorption by 26.5%, polymolecular sorption by 23.9% and monomolecular sorption by 33.1% at saturation, compared with the untreated wood. Regression analysis of the EMC values at saturation revealed that the variation shown in the water sorbed at the polymolecular level plays the main role in the variation in total water sorbed. In addition, it was found that only the reduction in monomolecular sorption can be primarily attributed to the decrease in site accessibility.
