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 the adsorbate on the surface of the adsorbent. This process differs from absorption, in which a fluid (the absorbate) is dissolved by or permeates a liquid or solid (the absorbent), respectively. Adsorption is a surface phenomenon, while absorption involves the whole volume of the material. The term sorption encompasses both processes, while desorption is the reverse of it.

In the present book, twelve typical literatures about packaging and adsorption published on international authoritative journals were selected to introduce the worldwide newest progress, which contains reviews or original researches on bentonite clay, activated carbon, adsorption enthalpy, protein and surfactant adsorption, adsorption chillers and adsorption spillover, etc. We hope this book can demonstrate advances in packaging and adsorption as well as give references to the researchers, students and other related people.
