Definition of adsorption?

Adsorption is the process in which molecules or particles adhere to the surface of a solid or liquid material. This can occur through physical or chemical interactions, and the adsorbed molecules are typically held onto the surface by weak forces such as van der Waals forces or electrostatic interactions. Adsorption is commonly used in various industrial processes, such as in water purification, gas separation, and catalysis.

Adsorption is the adhesion of atoms, ions, or molecules from a gas, liquid, or dissolved solid to a surface. This process creates a film of adsorbate on the surface of the adsorbent. Adsorption is a surface phenomenon, and the amount of adsorbate that can be adsorbed on a given surface is dependent on the surface area of the adsorbent. The process of adsorption is driven by the surface energy of the adsorbent, which is the energy required to create a new surface. The higher the surface energy, the greater the driving force for adsorption.
