Importance of adsorption
WitrynaAdsorption isotherms are the graphs which describe the interaction of adsorbates with adsorbents. That is the amount of adsorbate on the adsorbent as a function of its … Witryna27 cze 2014 · The reason is that for the successful adsorption of the enzyme to occur, some certain conditions must be met, among which an enzyme-carrier affinity is most important. This is assured by the presence of the specific active groups on the carrier, which enable the generation of the enzyme–carrier interactions.

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 (solute )* on the surface of the adsorbent(solvent). This process differs from absorption, in which a fluid (the absorbate) is dissolved by or permeates a liquid or … Zobacz więcej The adsorption of gases and solutes is usually described through isotherms, that is, the amount of adsorbate on the adsorbent as a function of its pressure (if gas) or concentration (for liquid phase solutes) at … Zobacz więcej Characteristics and general requirements Adsorbents are used usually in the form of spherical pellets, rods, moldings, or monoliths with a hydrodynamic radius between 0.25 and 5 mm.
