摘　　要：利用空气氧化处理法对沥青基球状活性炭进行了改性。改性结果表明,在空气氧化处理的过程中,部分的微孔结构遭到了破坏。并且随着氧化强度的增强,沥青基球状活性炭的比表面积减小,但总孔容增加。中孔孔容的增加比较明显。与此同时,沥青基球状活性炭对苯酚的吸附性能下降。In this paper,pitch-based spherical activated carbon（PSAC） was modified by the air-oxidation treatment. The results showed that some of the micropores were destroyed by using the air-oxidation treatment. As the intensity of air-oxidation treatment increased,the surface area of the PSAC decreased, but its total pore volume increased. And its mespores volume increased remarkably. The adsorption perfor-mance of the PSAC for the phenol decreased as the intensity of air-oxidation increased.
