Adsorption Capacity - an overview | ScienceDirect Topics

Adsorption capacity, (or loading) is the amount of adsorbate taken up by the adsorbent per unit mass (or volume) of the adsorbent. 1 The ,adsorption capacity, of a solid desiccant for water is expressed as the mass of water adsorbed per mass of desiccant. There are three water-,adsorption capacity, terms used as follows (Campbell, 2000):Static equilibrium capacity: the water capacity of a new ...
