Adsorption Of Water Vapor

The adsorption and desorption of water vapor by wheat was measured by means of a McBain sorption balance. Curves are obtained showing the rate at which moisture is adsorbed by kernels of wheat directly exposed to a humidified atmosphere, and a theory is advanced to account for the rate of adsorption. It is shown that the rate of adsorption is governed largely by the time taken for the moisture to diffuse up to the surface of the wheat. Under storage conditions, this is much greater than the time required for the moisture to penetrate the kernel of wheat from its surface.

A Direct Method

A direct method used for measuring the adsorption of water vapor on cellulosic materials and in which a number of improvements have been made is described. It is ensured that no vapors other than water are present no matter how long a time is required for the establishment of equilibrium. The adsorption and desorption isotherms of standard cellulose, spruce wood, surgical cotton, Kodak rag cellulose and bleached sulphite have been measured, and the data which indicate the time required for the establishment of true equilibrium have been given. The data of Urquhart and Williams (6, 7) for standard cellulose determined by an indirect method in 1926 have been shown to be correct.
