Summary

  1. 1.

    We investigated the adsorption kinetics of water vapor on NaA and NaX granulated zeolites at a concentration of 1.75 mg/liter, 20°C and different carrier-gas velocities.

     
  2. 2.

    At a current velocity of 1.4 m/sec the approximate value of the diffusion coefficient may be calculated from the equation for internal diffusion, i.e., on the assumption that external mass exchange is infinitely rapid.

     
  3. 3.

    A measurement procedure with more efficient consumption of carrier-gas is recommended.
