WebDubinin-Radushkevich isotherm is expressed as follows [ 16 ]: where ϵ is Polanyi potential, is Dubinin-Radushkevich constant, is gas constant (8.31 Jmol −1 k −1 ), is absolute temperature, and is mean adsorption energy. WebView history. 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 of materials. The observations are very often referred to as physical adsorption or physisorption. diy small greenhouse cheap https://alexeykaretnikov.com
