摘　　要：以除尘灰分离炭粉为原料,确定了制备颗粒活性炭的最佳工艺,并对制备的颗粒活性炭进行不同的改性处理和对不同有机蒸气的吸附实验。利用X-光电子能谱仪分析了改性处理后的表面化学性质。吸附实验证明,活性炭的比表面积、表面化学性质和有机物的性质对吸附过程产生影响。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.
