TLDR
The micropore filling appears to occur in two stages: 1) a primary process in pores of molecular dimensions and 2) a secondary, or cooperative, process in somewhat wider pores as mentioned in this paper.About:

Determination of pore size and pore size distribution: 1. Adsorbents and catalysts
TL;DR: In this article, the structural factors of the pores are discussed as well as the methods for evaluation of the pore size distribution with molecular adsorption (molecular resolution porosimetry), small angle X-ray scattering, mercury poro-simulation, nuclear magnetic resonance, and thermoporositmetry.
Journal ArticleDOI
Origin of superhigh surface area and microcrystalline graphitic structures of activated carbons
TL;DR: In this paper, a simple method for determining specific surface area for microporous carbons, which is designated the subtracting pore effect (SPE) method, was proposed.
Journal ArticleDOI
Adsorption of phenol onto activated carbons having different textural and surface properties
TL;DR: In this article, the effect of surface properties on phenol adsorption in aqueous phase onto activated carbons (ACs) having different textural and surface properties has been considered.
Journal ArticleDOI
Liquid-phase adsorption of dyes and phenols using pinewood-based activated carbons
TL;DR: In this article, the adsorption equilibria and kinetics of three dyes and three phenols (phenol, 3-chlorophenol, and o-cresol) from aqueous solutions on such carbons were examined at 30°C.
Journal ArticleDOI
Modification of the surfaces of a gasactivated carbon and a chemically activated carbon with nitric acid, hypochlorite, and ammonia
TL;DR: In this article, a gas-activated carbon and a chemically activated carbon were chemically modified by oxidation with nitric acid or hypochlorite, and the parent and modified carbons and chars were characterized by different techniques, such as acid/base adsorption, TGA/MS, FT-IR, and porosimetry.

Investigations of a complete pore structure analysis
TL;DR: In this article, a method for determining the pore volume and pore surface distributions of micropores is proposed, which is an extension of the "t-method" of de Boer and his co-workers.
