| Abstract: | The adsorption property and the surface properties of the modified coal - based activated carbon were investigated. The experiment results showed that the number of surface acid function groups changed greatly, and the modified coal - based activated carbon had better adsorption behavior for p - nitrophenol. The adsorption efficiency of the coal -based activated carbon by modified with H2SO4 and K2Cr2O7 can be improved obviously. |
