WebTo measure the specific surface area of pore materials, N2 adsorption method was applied to analyze the pore structure of samples with pore diameters from 0.5 to 40 nm. The specific surface areas of these samples were obtained by the multi-point BET method. The results show that the ranges of relative pressure are closely related to the pore diameter of … Web28 aug. 2024 · Multi-point BET The slope and y-intercept can be obtained using least squares regression. The monolayer capacity X m can be calculated with 2.3.3 . Once X m is determined, the total surface area S t can be calculated with the following equation, …
WebThe BET (Brunauer, Emmett and Teller) theory is commonly used to evaluate the gas adsorption data and generate a specific surface area result expressed in units of area per mass of sample (m 2 /g). The technique is referenced by several standard organizations such as ISO, USP and ASTM. T Plot Method Between Two WebAbstract. The theoretical background of the adsorption isotherm equation of Brunauer, Emmett and Teller is reviewed, together with the experimental techniques available for measuring physical adsorption of gases by solids. Examples are given to show how such measurements are used to determine the specific surface of constructional materials.
WebThe BET method is applicable for solids with pore diameters from above ∼4 nm. Below 8 nm the calculations are believed to be inaccurate. It is accepted that BET gives the most accurate results for the mesopores (160 nm to about 10,000 nm). The range of relative humidities (p/p 0) at which the BET method applies is from about 0.05 to 0.35. For ...
