Abstract: The application of the conventional methods for determining the textural properties of solids, as the Dubinin-Radushkevich (DR), Dubinin-Astakov (DA), BET and many others, is based in the linearization of the corresponding mathematical equation. Consequently, such application is only restricted to the relative pressure range where the linear relation may exist. In this way, very often, when the textural parameters calculated from that linearization are used together with the corresponding equation for reproducing the adsorption isotherm shape, very poor agreement with the original experimental data are obtained. In this work, a new procedure is proposed as an alternative tool, very flexible and easy to apply, which permit to obtain the values of the textural parameters, being capable of adequately reproduce an experimental adsorption isotherm in the overall range of relative pressures.
