  1. 1.

    Desorption (adsorption) with concave (convex) isotherm, a problem of considerable practical interest, is discussed.

  2. 2.

    It is suggested that the broken-line isotherm gives a better approximation to the actual isotherm than does the rectangular isotherm.

  3. 3.

    A unified approach to desorption with such an isotherm is suggested.

  4. 4.

    An approximation for the initial second-stage concentration distribution is suggested, and the limits of its applicability are discussed.
