BET theory - Wikipedia. Brunauer. In 1. 93. Stephen Brunauer, Paul Hugh Emmett, and Edward Teller published the first article about the BET theory in the Journal of the American Chemical Society. It usually uses static volumetric principle (like V- Sorb 2. TP), also has gas flowing technology can determine surface area data. Concept. This plot is called a BET plot. The linear relationship of this equation is maintained only in the range of 0. The value of the slope A. The following equations can be used: vm=1. A+I(3). The total surface area Stotal. Furthermore, the authors made five assumptions. Hence, the heat of adsorption is EL is equal to the heat of liquefaction.

Thesaurus Antonyms Related Words Synonyms Legend: Switch to new thesaurus. At the saturation pressure, the molecule layer number tends to infinity (i. Let us assume that the adsorption rate Rads,i- 1 for molecules on a layer (i- 1) (i. For the adsorptions, these constant are assumed similar whatever the surface. Assuming an Arrhenius law for desorption, the related constants can be expressed aski=exp. If the quantity of adsorbed water vapor is measured at different levels of relative humidity a BET plot is obtained. In case of cement paste hardened in water (T = 9. It follows thus SBET=1. Brunauer–Emmett–Teller (BET) theory aims to explain the physical adsorption of gas molecules on a solid surface and serves as the basis for an important analysis technique for the measurement of the specific surface area. However, the article on Portland cement states that . BET theory can be applied to estimate the specific surface area of activated carbon from experimental data, demonstrating a large specific surface area, even around 3. Porous inorganic materials such as mesoporous silica and layered clay minerals have high surface areas of several hundred m. H.; Teller, Edward (1. Journal of the American Chemical Society.
