| Abstract: | The sorption of naphthalene and naphthol from water solutions by peat, chernozem, and humic and fulvic acids was studied. The sorption isotherms of naphthalene and naphthol by chernozem corresponded to the Langmuir isotherms. More complex nonlinear isotherms were obtained for peat. Binding of naphthalene and naphthol by humic and fulvic acids can proceed through hydrophobic interactions with aromatic fragments of humic substances and hydrogen bonds between the polar groups of humic molecules and naphthol OH groups. |
