摘　　要：活性炭具有特殊的物理化学特性,常被用作吸附剂,广泛应用于工业、饮用水净化、废水处理等领域,并取得显著的成效。目前水污染物种类繁多,对水质要求高,传统的活性炭在使用方面具有一定的局限性。国内外的很多研究表明,通过对活性炭进行表面改性,可提高其对特定物质的吸附能力,活性炭的改性由此成为热点。从化学改性、物理改性、微生物改性等三大方面综述了国内外活性炭的改性技术,概括了不同改性方法的特性,并比较了不同改性技术改性前后对水中特定吸附质吸附性能的差异,为活性炭的改性研究提供参考和依据。Activated carbon is often used as adsorbent, widely used in industrial, drinking water purification, wastewater treatment and other fields for its special physical and chemical properties, achieving remarkable results. Currently, the application of the activated carbon is limited for the complexity of the contaminants in the water treatment and the high demand for the water quality. Researches both at home and abroad have shown that the adsorption properties of activated carbons can be improved through the surface modification and activated carbon modification has become a hot topic in order to prepare a modified activated carbon which has a special affinity for the different pollutants in water treatment. In this paper, the modification methods and the properties of activated carbon from domestic and abroad are summarized, including chemical modification methods, physical modification methods and micro-organisms modification methods. At the same time, the adsorption capacity differences between the activated carbon and the modified ones are compared in order to provide reference and basis for the study of activated carbon modification.
