www.seas.upenn.eduΩ is expressed in J kg 1 of solid adsorbent. Physically, the grand potential is the free energy change associated with isothermal immersion of fresh adsorbent in the bulk fluid. The absolute value of the grand potential is the minimum isothermal work nec-essary to clean the adsorbent. Since adsorption occurs spontaneously, the cleaning or

chemistry.du.ac.inAdsorbent layers and stationary phases The standard silica coating (silica 60 with a mean pore diameter of 60 A° ) is the most commonly used adsorbent in TLC, although for some very sensitive substances less active adsorbents such as aluminum oxide are preferred to prevent sample decomposition. Moreover, in the early days, the use
Adsorption Basics: Part 1 - AIChE
www.aiche.orgprocess, the solid is called the adsorbent and the solute is known as the adsorbate. Commercial adsorbents are highly porous, with pore sur-face areas ranging from about 100 to 1,200 m2/g. The large surface area allows a large amount of adsorption relative to the weight of the adsorbent, well in excess of its own weight in some cases.
