摘　　要：基于大气污染日益严重的现状,从制备和改性两个领域阐述了活性炭吸附VOCs的吸附机理和研究进展。在制备领域主要提及原料选择、炭化和活化过程,并着重探讨活化过程对活性炭成孔性的影响。改性领域以化学改性为主阐述了国内外先进的活性炭改性技术和进展,并比较了不同改性方法对VOCs吸附性能的影响。为以活性炭为原料吸附VOCs的研究提供参考和依据。Based on the present situation of increasing atmospheric pollution, the adsorption mechanism and research progress of the adsorption of VOCs by activated carbon were described from two fields of preparation and modification. The selection of raw materials, carbonization and activation process were mainly mentioned in the preparation field, and the effect of activation process on the porosity of activated carbon was discussed. In this paper, the modification of activated carbon technology and the preparation of advanced activated carbon are described in the field of chemical modification, and the influence of different modification methods on the adsorption performance of VOCs is compared. The study provides reference and basis for the adsorption of VOCs by activated carbon.
