| 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。

| 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. |
