摘　　要：活性炭的微结构和表面化学特性对其吸附性能产生显著影响 .概述了通过调整活性炭孔隙结构 ,引入化学基团 ,改变其酸碱度和极性 ,提高其吸附极性分子能力的方法 .介绍了炭表面化学结构 ,分析了炭微结构、表面基团和吸附质性质对吸附过程的影响 .对近年来活性炭表面的改性在吸附 SO2 和 VOCs的实验研究进行了讨论 .The surface properties and microstructure of activated carbon play a significant role on adsorption.The present paper gives a review of improving the adsorptive capacity on polar molecules through changing microporosity and modifying chemical surface properties of activated carbon.The functional groups on surface of activated carbon are described in this paper.Effect of porosity and surface oxygen groups on adsorption especially of SO 2 and VOCs on modified activated carbons are discussed as well.
