Surface area of adsorbent
WebAug 30, 2024 · Brunauer–Emmett–Teller (BET) surface area is measured by specific surface area of the adsorbent. BET surface area is measured by using non-corrosive gases like $\ce{N2}$, $\ce{CO2}$, $\ce{Ar}$ etc. BET surface area depends on size and number of gas molecules adsorbed. Langmuir surface area depends on adsorption capacity of the … WebApr 3, 2024 · Nature of Adsorbent: Since adsorption is a surface phenomenon, adsorption increases with the increase in the surface area of the adsorbent. More finely divided or rougher the surface of adsorbent, the greater will be the surface area and hence the greater will be the adsorption.
