    Notes: Abstract The problem of diffusion controlled adsorption kinetics is solved by orthogonal collocation for the Henry and the Langmuir isotherms. The dependence of the surface concentration of a surfactant on time is described by explicit formulae for the whole range of time. The results are compared with those obtained by power series expansions and finite difference methods and have a high accuracy for any time value. The method of orthogonal collocation has been shown to be very effective. It is suitable for applications to similar problems.

    Description / Table of Contents: Zusammenfassung Es wird das Problem der diffusions-kontrollierten Adsorptionskinetik durch Anwendung eines impliziten Differenzenverfahrens gelöst. Dabei können bei der Berechnung alle Formen von Adsorptionsisothermen zugrunde gelegt werden. Rechenbeispiele für die Langmuir-, Freundlich-, Volmer-, Frumkin- und van-der-Waals-Isotherme werden angegeben.
    Notes: Summary The problem of diffusion controlled adsorption kinetics is solved by application of an implicite difference method. Thereby all forms of adsorption isotherms can be used in the calculations. Computation examples are given concerning Langmuir, Freundlich, Volmer, Frumkin, and van der Waals isotherms.
