Part Two: Definitions and Concepts
Adsorption means attachment to the outside of something. In the case of aqueous solutions one can consider adsorption of molecules, ions, and colloidal particles onto the surfaces of fibers, fiber fines, and fillers. Except for the special case of chemi-sorption, one does not have to assume that any chemical reaction takes place. Rather, the adsorbate (the thing that is adsorbed) is attracted to the surface by the net effects of electrostatics, London dispersion, and solvent structure (or entropy).
