ABSTRACT

Adsorption is defined as a spontaneous process during which one or more components of system concentrates on the interfacial region. Adsorption is, in most cases, a transient process, involving a solid and a fluid. The use of a solid is the main distinguishing feature from other processes such as absorption, distillation, or extraction. Solids are able to adsorb only traces of solute, therefore making this method useful for dilute solutions.
