Principle
In general, the term adsorption is used to describe the
attachment of gases or dissolved substances to the surface of a
solid or liquid. At constant temperature, the quantity of adsorbed
substances is a function of the type of system investigated and the
partial pressure and / or concentration of the substance concerned.
The correlation is described by a number of adsorption isotherms.
The rivalidity is to be investigated experimentally.
