WebAbstract. Adsorption reactions in soils are the processes by which solution constituents become attached to the surfaces of soil particles and are the means of satisfying the forces of attraction that exists at the surfaces. These processes are governed by the surface properties of inorganic and organic components of soils and the associated ...

Webadsorption. The ultimate in favorable isotherms is irrevers-ible adsorption, where maximum adsorption is reached at very low partial pressures. Note that an isotherm that is favorable for adsorption is unfavorable for desorption. In particular, the most favorable isotherm is the most difficult to desorb — hence the name irreversible. 30°C 0°C
