Аннотация: The structure of Fe-containing components of the carbon adsorbent prepared from the residue after carbon dioxide lignin reforming stimulated by microwave radiation was studied before and after the m-cresol sorption. As shown by X-ray photoelectron spectroscopy (XPS), the prevalent state of iron in the samples is Fe 3+ . The revealed “apparent decrease in the iron content” after the adsorbent treatment with cresol is due to the forma-tion of surface complexes partially absorbing the emitted photoelectrons. The Mössbauer spectra show that the iron-containing phase of the initial adsorbent contains a fraction of Fe 0 atoms (≈7%), which are oxidized from 0 to 3+ oxidation state upon m-cresol adsorption. This result can be attributed to the occurrence of reactions yielding surface iron alcoholates.
