  1. 1.

    It is suggested that the constants that characterize adsorption dynamics in the layer-by-layer adsorption dynamics model be expressed in terms of length. The kinetic constant is defined as the equilibrium adsorption layer Le where the output concentration is numerically equal to the concentration in equilibrium with the mean adsorption level of that layer.

  2. 2.

    The initial equation combines the features of a material-balance equation and the adsorption kinetics and isotherm.

  3. 3.

    The results of numerical calculations for a convex, a linear, and a concave adsorption isotherm agree closely with experimental data.
