4. Adsorption theories
There are many theories of adsorption, but in this article only those are given which can be used most directly to characterize the texture of powdery or porous materials (specific surface area and pore size distribution).
Although Langmuir's theory was developed for chemisorption, it is mentioned here because it forms the basis of the physical gas adsorption theory of Brunauer, Emmett and Teller.
