| Abstract: | The optimize preparating process for granular activated carbons from fly ash was defined.The obtained GACs were then modified through different methods and the adsorption experiment of the modified GACs for different organic vapors was carried out.The chemical properties on the surface of the GACs were determined by X-ray photoelectron spectroscopy(XPS).It was proved that the specific surface and chemical properties of GACs as well as the properties of the organic all have effects on the process of adsorption. |

| Keywords: | GACs modification surface characteristics adsorption fly ash |
