TL;DR: In this article, the adsorption of phenol and substituted phenols, such as 4-nitrophenol, 2,4-dinitrophenols, 4-chlorophenol, and 4-dichlorophenol in aqueous solution, has been determined at 298 K on a series of activated carbons, prepared from olive stones, having a wide range of burnoff (8-52%) and micropore size distributions.

TL;DR: In this paper, the authors used the adsorption of carbon dioxide at 273°K to evaluate the microporous structure of the adsorbent corresponding to the primary mechanism (narrow micro-porosity).
Abstract: The CDS method can be used to determine the non-microporous structure of porous solids such as activated carbons. This method uses the adsorption of carbon dioxide at 273°K to evaluate the microporous structure of the adsorbent corresponding to the primary adsorption mechanism (narrow micro-porosity). From the adsorption isotherm both the micropore volume and the characteristic energy can be calculated and, by the appropiate correction in affinity coefficient and adsorption temperature, the corresponding isotherm for the microporosity for any adsorptive can be constructed. If this micro-porous isotherm is subtracted from the experimental isotherm for the given adsorptive, the corresponding residual isotherm may be analyzed by any of the usual methods (BET, t, α, etc.). The CDS is a very simple (from the experimental point of view) method to evaluate the non-microporous (external) surface area of activated carbons improving its determination with the advantage over other methods of subtracting always the same type of porosity (primary micropore filling in narrow micropores) and being applicable to any type of adsorptive used in the characterization of this sort of adsorbents.
