Evaluation of BET specific surface area of No. 3 activated carbon (Type I adsorption isotherm)
BELSORP
[Information] Underestimating the specific surface area! An introduction to the evaluation of the BET specific surface area of activated carbon (Type I adsorption isotherm).
This document introduces the evaluation of the BET specific surface area of activated carbon (Type I adsorption isotherm) using graphs and other materials. Activated carbon and zeolites with micropores typically exhibit Type I adsorption isotherms. When evaluating the BET specific surface area of these materials, the large curvature of the micropores and the constraints on the packing of the adsorbate prevent the formation of multilayer adsorption, thus invalidating the BET theory and leading to an underestimation of the specific surface area. This document explains the evaluation method for the BET specific surface area of such Type I materials. *For more details, please refer to the PDF document or feel free to contact us.*
