| description | A critical analysis of different methods for determining surface fractal dimensions using adsorption measurements is presented. A new method for calculating surface fractal dimensions from capillary condensation or mercury porosimetry data is proposed. This method does not use any model of adsorption on the fractal surface. It is based on the thermodynamic relationship between the surface area of the interface and the amount of the adsorbate. The formulae obtained for surface fractal dimensions do not contain any additional parameters except the experimental data. A typical example of calculating the surface fractal dimensions of an active carbon sample is presented. |
