摘　　要：介绍了活性炭(AC)在净水过程中微生物的繁殖,概述了银抗菌机理的研究进展。阐述了载银AC(AC/Ag)的制备现状,指出负载纳米银的AC/Ag具有更强的抗菌性能。归纳了银的价态、银颗粒尺寸等因素对AC/Ag抗菌的影响,总结了AC孔结构、AC表面化学性等因素对AC/Ag的影响,展望了AC/Ag的发展趋势。This review summarizes the progress of silver-loaded activated carbon （AC/Ag） for the deep purification of potable water. The propagation of microorganisms on AC and the antibacterial mechanisms of silver are firstly discussed. Then, the preparation methods for AC/Ag are elaborated, in which the nano-silver loaded AC/Ag has been proved to have stronger antibacterial characteristic. The influence of valence state and particle size of silver, the pore distribution and surface chemical properties of AC on the antibacterial and inhibitory properties are discussed. Furthermore, the developmental trend of AC/Ag is proposed.
