| 摘 要： | 1. INTRODUCTION Activated carbons (ACs) have been widely used as adsorbents in environmental protection, e.g. removing organic or inorganic pollutants from liquid effluents and voltaic organic compounds (VOCs) from polluted air. It has been well known that the adsorptive capacity of ACs is not only determined by its textural properties (e.g. specific surface area, pore size distribution, pore volume), but also related to its surface chemistry. Many studies have demonstrated that the ad…

| Abstract: | This review focused on the recent reports related to the function, characterization and modification of oxygen-containing surface groups of activated carbon (AC). The Oxygen-containing surface groups were briefly described, and the most frequently used techniques for characterization of the oxygen-containing surface groups on ACs were also briefly stated. A detailed discussion of the effects of the oxygen-containing surface groups on the adsorptive capacity of AC was given. The recent progresses in modification of the oxygen-containing surface groups of AC were also reviewed. |
