By using Automatic Adsorption Balance(Model ASR-711 ) ,values of water vapor adsorption, at saturated state, of 9 major local made activated carbons were measured under relative pressure ( P/Ps = 100% ).

• 采用ASR-711型自动吸附天平测定了国产9个主要活性炭在相对湿度P/P_s=100%25时的饱和吸湿量,研究了活性炭的吸湿性与表面含氧基团,制造工艺、孔径分布之间的关系,以及具有代表性的活性炭在各种相对湿度下的吸湿速率、等温吸附线等参数。
