Abstract: 
Adsorption of aromatic and heterocyclic compounds from aqueous solutions on Mn(III), Pb(IV), V(V) oxides and activated carbon under static conditions has been studied. The energies of occupied and unoccupied orbitals have been used as correlation parameters between the electronic and adsorptive properties of organic molecules. Frontier-controlled adsorptive mechanism is postulated for interpretation of the observed correlations for the specific adsorption of organic compounds on low-bandgap adsorbents.
