摘    要:本文采用颗粒状活性炭(GH-A)作吸附剂,通过不同的前处理方法,以一氧化碳CO与空气的混合物为分离测定对象,用气固色谱法测定被活性炭充分吸附前、后的混合气体中CO的含量,对比评价几种前处理方法。结果表明,对CO的吸附量显著提高的前处理方法分别是研磨筛分至32—38目、酸洗、添加改性剂So而水洗则降低了活性炭吸附CO的能力。

关 键 词:活性炭  吸附  一氧化碳  前处理  大气污染物  空气净化

Abstract:In this paper,granular activated carbon is used as adsorbent after some kinds of different pre-treatments. Gas mixed by carbon monoxide and air is the object of study. Through the activated carbon's adsorption for CO measured by gas-solid chromatogr- aphy, the effects on activated carbon by the different pre-treatments we used are compared. The result showed the adsor ption ability to CO of activated carbon improved remarkably by these pre-treatments: grid and mesh analysis to 32-38 mesh , acid dip , adding modifier S . But water dip method reduced the activated carbon's adsorption ability to CO.
Keywords:Activated carbon  adsorption  carbon monoxide  pre-treatment
