Adsorption

There are two forms of adsorption - physical and chemical adsorption.

Chemical adsorption occurs when molecules form a strong chemical bond. The process is irreversible - a compound is formed.

Physical adsorption occurs when molecules are weakly attracted to each other (van der Waals’ forces). Physical adsorption is reversible - desorption is possible. This is the process by which ACE works.
