| 摘 要： | 主要研究了３种具有不同孔结构的沥青基球状活性炭对肌酐及ＶＢ１２的吸附性能，与ＢＥＴ比表面主孔结构进行了关联。结果表明，具有微孔结构的沥青基球状活性炭对小分子肌酐的吸附性能较好；具有中孔结构的沥青基球状活性炭对中分子物质ＶＢ１２具有较好的吸附性能；而中孔与微孔并存的沥青基球状活性炭对肌酐及ＶＢ１２都有较好的吸附性能。

| Abstract: | In this study,the adsorption properties to creatinine and VB 12 of pitch-based spherical activated carbon with different pore structures were investigated.The results showed that adsorption to creatinine was influenced by both BET surface area and pore volume,while that to VB 12 was mainly influenced by mesopore.Pitch-based spherical activated carbon with single micropore (PSAC-W) had better adsorption property to creatinine;pitch-based spherical activated carbon mainly containing mesopore (PASC-Z) had better adsorption property to VB 12 ;while pitch-based spherical activated carbon containing both micropore and mesopore (PSAC-WZ) had better adsorption property to both creatinine and VB 12 . |
