Sorptionsisotherme

Sorptionsisotherme refers to the relationship between the amount of a substance adsorbed onto a surface and the concentration of that substance in a surrounding solution or gas mixture. It is a fundamental concept in adsorption and sorption, describing the equilibrium state reached when the rates of adsorption and desorption are equal.

A sorptionsisotherme typically involves a plot of the amount of substance adsorbed (usually expressed as mass

In a typical sorptionsisotherme, the amount of substance adsorbed increases with increasing concentration until a saturation

Sorptionsisothermes can be classified into different types, such as Langmuir and Freundlich isotherms, depending on the
