| Abstract: | Adopting chemical activation method, the high specific surface area coal-based activated carbon was prepared from Taixi anthracite by KOH as activator. The influence of the ratio of KOH to carbon, activation temperature and activation time on adsorption properties were emphasized studied. The results show that high specific surface area coal-based activated carbon can be prepared when the ratio of KOH to carbon was 4, activation temperature was 800℃ and activation time was lh, which specific surface area was 3215m^2/g, iodine adsorption value was 2884mg/g and methylene blue adsorption value was 548mg/g. |
