WebBET theory is a well-known rule for the physical adsorption of gas molecules on a solid surface. In 1938, Stephen Brunauer, Paul Hugh Emmett, and Edward Teller published an article about the BET theory in a journal [1] for the first time; “BET” consists of the first initials of their family names. The concept of the theory is an extension ... WebMay 4, 2024 · The surface area of a sample is given by. S BET = ν m N s V. where ν m is the amount in the monolayer (given in c m 3 / g ), N is Avogadro's constant, s is the adsorption cross-section of the adsorbate ( 0.162 n m 3 for N X 2) and V is the molar volume of the gas ( 22.4 L / m o l ).

WebAdsorption is a process that occurs when a gas or liquid solute accumulates on the surface of a solid or a liquid (adsorbent), forming a molecular or atomic film (the adsorbate). It is different from absorption, in which a substance diffuses into a liquid or solid to form a solution. The term sorption encompasses both processes, while desorption is the reverse … Web利用上述吸脱和附数据绘制等温吸附和脱附曲线，纵坐标是吸附量（Quantity Adsorbed (cm3/g STP)，横坐标是Relative Pressure (P/Po)： 即：选中BooK2中的所有数据，菜单中的”Plot“，选择”Line+Symbol“，后得到如图所示的吸附脱附等温曲线：

WebThe material in the adsorbed state is called the adsorbate, while that present in one or other (or both) of the bulk phases and capable of being adsorbed may be distinguished as the adsorptive. In some cases of chemisorption (see §1.1.6) adsorptive and adsorbate may be chemically different species (e.g. in dissociative adsorption).
