Sorption of phenolic compounds may be a very complex process and lots of factors influence it. At the start , detailed chemical structure of phenols is presented with its consequence for physical properties, for instance , values of melting and boiling points, solubility in water, pKa and Log P. Also influence of activating and deactivating substituents on the properties is explained. On this basis, interaction with the foremost frequently used sorbents, for instance , chemically modified silicas, polymers and porous carbons, is described. Both sorbents characteristics including physical (porosity) and chemical properties (functional groups) and experimental conditions like concentration of solutes, contact time, temperature, solvent effects and presence or absence of oxygen are taken under consideration . the reasons of irreversible adsorption and oxidative coupling phenomena are included. The mechanisms of phenolic compounds sorption are described.
