Adsorbed
Definition
Bound and retained upon the surface or interface of a solid or liquid substrate (adsorbent) via intermolecular forces or chemical bonds. The term describes the state of molecules, ions, or atoms originating from a fluid phase that have left the bulk medium to form a thin, concentrated layer at the boundary between two phases.
