摘　　要：活性炭表面官能团的种类与数量决定了活性炭的表面化学性质,而化学性质决定了活性炭的化学吸附特性。通过改变活性炭表面官能团的种类与数量、消除某些基团或者负载增加活性中心,可以改善活性炭对特定吸附质的吸附能力。论述了活性炭表面化学性质的氧化、还原、酸碱、等离子体、金属负载和电化学等改性及其应用研究进展。The surface chemical properties of activated carbon are related to functional groups and chemical compounds on the surface, which further determine the chemical absorbing characteristic of the activated carbon. Substantial improvement in the activated carbon＇ s ability to absorb specific adsorbates can be made by way of increasing or decreasing the number and types of base groups and active centers, removing completely via surface oxidizing, and reducing and loading pretreatment. The characteristics of the surface modification of the activated carbon such as oxidation, reduction, metal loading, acid-base treating, plasma and electrochemical were reviewed as well as its applications development.
