Importance of adsorption

Witryna15 sty 2024 · UV–vis is widely applied as an agile technique to quantify the concentration of compounds dissolved in liquid samples. Still, it can also be employed to characterize nano-size adsorbent suspension [28].Graphene derivatives are often characterized by UV–vis, and present an adsorption peak at 230–240 nm and a shoulder at 270–335 … Witrynaadsorption. 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
