Conclusions

  1. 1.

    An adsorption balance apparatus for determining the adsorption and desorption isotherms of vapors of relatively nonvolatile substances at normal temperatures was described.

     
  2. 2.

    The peculiarities of experiments with vapors of relatively nonvolatile substances lie in the displacement of extraneous, less adsorbed gases from the walls of the adsorption apparatus, unheated during evacuation. This is responsible for the noncoincidence of the adsorption and desorption branches of the adsorption isotherm.

     
  3. 3.

    The conditions of determination of reproducible adsorption isotherms, when coincidence of the adsorption and desorption branches of the isotherm is observed, were discussed.
