Abstract:
A simple relation between the extent of filling of pore volume and the adsorption potential is obtained from the equation describing vapor adsorption in micropores with nonuniform size distribution: W(A) ∝ AD-3, where D is the fractal dimensionality. A comparative analysis of this formula and the formula used to estimate the fractal dimensionality from the SAXS data shows that they are functionally similar. The formula obtained was used to process the experimental nitrogen-adsorption isotherms (77 K) for a number of carbon sorbents. The values of the fractal dimensionality for the micropore systems of the carbon materials studied range from 2.61 to 2.72.
