conditions were 0.1 g of activated carbon, 70 °C of adsorption temperature and 30 minutes of adsorption time. Physical characterization of the activated carbon obtained was performed by scanning electron microscopy (SEM). The results present that the activated carbon of rice husk possesses a high apparent surface area (S BET = 336.35 m 2/g). They thus encourage the use of activated carbon of

BET is the Brunauer–Emmett–Teller theory Particular

In this work, we provide a comprehensive analysis of the BET areas for both model slit pores and crystalline porous materials using the grand canonical Monte Carlo simulation. Based on extensive simulation data for nitrogen adsorption at 77 K and the conventional models of materials characterization, we find no simple correlation between the BET and geometrical surface areas. For …

A comprehensive analysis of the BET area for nanoporous

The determination of specific surface by means of the BET theory is based upon the phenomenon of physical adsorption of gases on the external and internal surfaces of a porous material. Such a material which is surrounded by and in equilibrium with a certain gas which has a certain temperature, T, and relative vapour pressure, p/po, adsorbs physically a certain amount of gas. The amount of
