Fractal geometry concept in physical adsorption on solids

الملخص EN

The different experimental and theoretical methods of determining the fractal dimension (D) of solid adsorbents are reviewed.

Attention is paid to the methods of calculation for D based on the results of a single adsorption isotherm measurement.

A new derivation of the fractal analog of the FHH adsorption isotherm equation is given and a new model of adsorption on pore and surface fractals is proposed.

Some of the methods are illustrated, applying our recently developed numerical algorithms.

Key words: fractal dimension; adsorbents; adsorption isotherm; pore and surface fractals.
