The dynamic competitive adsorption of organic vapors on ACP-P

The dynamic competitive adsorption of a new fiber ACF-P for binary organic vapor mixture was preliminary investigated by gas chromatography, The competitive adsorption behaviors on various ACFs used, in different dynamic adsorption conditions and for different binary organic vapor mixtures were compared in this paper. The results show that ACF-P, as with ACF-W, can remove both components of organic vapor mixture with about 99% of removal rate before first breakthrough point. In dynamic competitive adsorption, the more weakly adsorbable component is earlier to breakthrough and produces a rolling up in the breakthrough curve because the displacement and desorption of stronger adsorbate. The dynamic competitive adsorption ability of a vapor component in mixture is mainly related to its boiling point as well as its structure at some time. The preparation temperature of ACF-P and adsorption condition have effect on competitive adsorption.
