【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。更多还原

【Abstract】 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 the total pore volume increased. And the mesopores volume increased remarkably. The adsorption performance of the PSAC for the phenol decreased as the intensity of air-oxidation increased.更多还原
