摘　　要：本文以沥青中间相为原料,采用KOH化学活化法,获得了比表面高达2363m^2/g的炭分子筛(CMS);用2400吸附仪N_2吸附测定了其孔结构,并研究了其对六价铬(Cr_(VI))及Au(CN)^-_2离于的吸附性能。结果表明。其平均孔径为24.7(?),微孔及总孔容积大大高于活性炭,其吸附容量和吸附速度也大大优于活性炭。A unique carbon molecular sieve (CMS) having a high specific surface area exceeding 2363m^2/g was developed in our laboratory. The carbon was made by chemical activatin route in which pitch mesophase was reacted with excess potassium hydroxide. The porous structure of GMS was measured by the BET method usiug ASAP 2400 and its adsorption properties to Gr_((Ⅵ)) and Au (CN)_2^- ions were studied. The results show that CMS has an average pore diameter of 24.7(?). Its total pore volume and micropore volume capacity are much larger than those of active carbon and its capacity and velocity of adsorption are much better than those of active carbon.
