Adsorption Capacity - an overview | ScienceDirect Topics
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 ...

15/1/2017, · The results concluded that ,adsorption, of Pb (II) ions increased with an increase in pH of the solution to a maximum around a neutral pH (7.0), and then decreased as the pH became more basic due to the precipitation of some Pb (II) ions. The results also indicated that cation exchange was the main ,adsorption, mechanism for ,acid,-activated clays .
