| 摘 要： | 通过活化添加二茂铁的沥青球，制得了比表面积在1000m2／g左右的中孔比较发达的沥青基球状活性炭。其中扎面积可达187m2／g，中孔孔容达0。304cm2／g，占总孔容的44％，中扎扎径主要分布在30A～50A及300A～500A处添加二茂铁后制得的沥青基球状活性炭与不添加二茂铁的沥青基球状活性炭相比，对VB12的吸附量有大幅度的提高。

| Abstract: | Pitch -based spherical activated carbon (PSAC) which specific surfacearea was about 1000 m2/g was prepared through adding ferrocene into the starting coaltar pitch' Its pore area reaches to 187m2/g, the mesopore vo1ume reaches to 0. 304cm3/g, owning 44 percent of the total volume of the pore. The results showed that the pres ence of ferrocene was beneficial to the formation of mesopore. especially those of 300A~ 500 A. The adsorption capacity of 'this PSAC containing ferrocerne to VB12 was quite 1arger than that without adding ferrocene. |
