Geometrical isomers, surface properties

Adsorptiou ou the carbon black surface depends mainly on the geometry of the adsorbate molecules aud their polarizability. Thus, graphitized carbon black is an ideal adsorbent for separation of isomers of similar physical properties but of different geometrical structures, because of its surface homogeneity [18]. Chemical modification of carbon black, on the other hand, enhances specific adsorption affinity by virtue of the presence of different functional groups on its surface [17,19].
