Adsorption method is one of the important methods of wastewater treatment.Wastewater is treated by conventional process,and the effluent also contains some refractory organic matter,free chlorine and some trace met-als such as Hg,Ag,Cr,Sb,As,most of which can be removed by adsorption.The decontamination efficiency and cost of adsorption method largely depend on the adsorbent.The most common adsorbent is activated car-bon.Theoretical study on adsorption method for wastewater treatment of research results is rare at home.However, the study of adsorbents accounts for a large proportion in more than a decade of research.%吸附法是废水处理的重要方法之一,污水经常规废水处理后,出水中还残留一些难降解有机物、游离氯及一些微量金属如汞、银、铬、锑、砷,利用吸附法能除去大部分这些物质.吸附法的去污效率、成本在很大程度上因吸附剂而不同,最常见的吸附剂是活性炭.吸附法用于污水处理的理论研究国内研究成果还不是很多,但在国内近十多年的研究中,吸附剂的研究占了很大的比例.
