A Kinetic Method for Determining Desorption Isotherms of Water on Clays1

  1. J. W. Odom and
  2. P. F. Low2



A method of using Knudsen cells to measure the vapor pressure of water in clay-water gels is described. The vapor pressures obtained at each mass ratio of water to clay using Knudsen cells are similar to those obtained by equilibration with saturated salt solutions and may be used in the same way.
