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
