Abstract A new approach is presented for determining the surface phase capacity and the distribution function in liquid adsorption on heterogeneous solid surfaces. This approach deals with statistical analysis of the errors made by applying the so-called exponential equation of the adsorption isotherm. It is proved that such an analysis, which is suitable for all types of excess experimental isotherms, gives the answer to the dilemma of the reliability of the results obtained by means of the assumed adsorption model. Several experimental systems were analyzed to demonstrate the advantage of our approach.
