...Also, for adsorbents with many micropores, the adsorption equilibrium is often explained by the idea that the adsorbate fills the pores, and in this case the following Dubinin equation is a good adsorption equilibrium equation. Here, w is the amount of adsorption at partial pressure p , w0 is the adsorption space volume of the adsorbent, E is the characteristic energy of adsorption, and A is the adsorption potential. A can be expressed as A = RT log e ( p / p 1 ), where R is the gas constant, T is the temperature, and p 1 is the saturated vapor pressure of the adsorbate at that temperature. ... *Some of the terminology that refers to "adsorption potential" is listed below.

…また,ミクロ細孔を多量に有する吸着剤では,吸着質が細孔を充てんしていくという考え方で吸着平衡が説明されることが多く,この場合は吸着平衡式として次のドゥビニン式がよい。ここでwは分圧pにおける吸着量,w0は吸着剤の吸着空間容積,Eは吸着の特性エネルギー,Aは吸着ポテンシャルである。なおAは,Rを気体定数,Tを温度,p1をその温度における吸着質の飽和蒸気圧とすれば,A=RTloge(p/p1)で表される。… ※「吸着ポテンシャル」について言及している用語解説の一部を掲載しています。 出典|株式会社平凡社世界大百科事典 第2版について | 情報 |
