沥青基球状活性炭吸附性能的初步研究

通过对非极性有机物（苯）及极质有机构（氯仿）的动态吸附及对溶液中碘的吸附，初步研究了沥青基球状活性炭（ＰＳＡＣ）的吸附性能：作为对比研究了沥青基活性炭纤维（ＰＡＣＦ）和普通粒状活性炭（ＡＣ）与ＦＳＡＣ的吸附性能；结果表明，ＰＳＡＣ无论在气相还是液相吸附方面，其吸附性与ＰＡＣＦ相近，而明显优于ＡＣ。另外，亦从微观孔结构的角度初步探讨了造成它们吸附性能差异的原因。

PRELIMINARY STUDY ON ADSORPTION BEHAVIOURSOF PITCH-BASED SPHERICAL ACTIVATED CARBON

Dynamic adsorption behaviours of pitch-based spherical activated carbon (PSAC) to polar/non-polar organic compounds(chloroform/benzene)in vapor phase and adsorption capacity of PSAC to Iodine in liquid phase were investigated.the adsorption behaviours of pitch-based activated carbon fiber(PACF)and common spherical-activated carbon were also investigated for compare.The results indicated that the adsorption abilities of PSAC to either polar/non-polar organic compounds in vapor phase or iodine in liquid phase were better and similar to those of Pitchbased activated carbon fiber(PACF),but rather higher than those of commercial activated carbon(AC)in addition,the different adsorption properties among PSAC,PACF and AC were also briefly discussed based on their pore structures.
