Conclusions

  1. 1.

    An analysis has been made of such basic concepts of physical adsorption as the total and excess adsorption, through which it has become possible to establish a physically justified boundary of the region of inhoraogeneity.

     
  2. 2.

    A relationship has been derived for the calculation of the extent of the region of inhomogeneity at the interface. Estimates have been performed for certain adsorption systems, indicating that the. thickness of the region of inhomogeneity is no more than a few units of molecular diameter of the adsorbate.
