Extensive studies of structure and energetic properties of the surface of the carbosils including from 0.8 to 35percent carbon were undertaken. The structural characteristics of the adsorbents under investigation obtained by nitrogen adsorption and desorption at 77 K, p-nitrophenol adsorption from aqueous solutions and flow microcalorimetry were presented. The results of the studies obtained by the electron paramagnetic resonance EPR and transmission electron microscopy TEM methods were also given. The obtained data allowed to determine morphology and topography of carbon deposits in the studied adsorbents as well as the effect of carbon amount on the modified silica surface on the energetic properties of the obtained complex adsorbents. The general studies, particularly, those on a large scale are of significant importance for further effective usage of original properties of carbon-mineral adsorbents. Knowledge of the complex adsorbent structure including morphology and topography of carbon deposits, surface properties is still poor compared with their present and perspective applications.
