Adsorption speed - Adsorption speed

Japanese: 吸着速度 - きゅうちゃくそくど
Adsorption speed - Adsorption speed

...Note that 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.
[Adsorption speed]
The speed of adsorption depends on the type of contact between the adsorbent particles and the gas or liquid, but the speed at which the adsorbate diffuses into the adsorbent particles is often important. In liquid-phase adsorption in particular, the speed of this intraparticle diffusion is a major factor in determining the residence time of the liquid in the device, i.e., the contact time between the liquid and the adsorbent.

*Some of the terms mentioned in the description of "adsorption rate" are listed below.

Japanese:

…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,ARTloge(p/p1)で表される。
[吸着速度]
 吸着の速さは,吸着剤粒子と気体または液体がどのような接触方式をとっているかによって決まってくるが,吸着剤粒子の中に吸着質が拡散して入っていく速度が往々にして重要である。とくに液相の吸着では,この粒子内拡散の速さが装置内の液の滞留時間,すなわち液と吸着剤の接触時間を決める大きな因子となっている。…
