Adsorbability of Active Carbon Fiber for Gaseous Benzene / 环境与健康杂志

ABSTRACT

Objective To study the adsorbability of active carbon fiber(ACF) for gaseous benzene and to use ACF for the determination of benzene in the air in future.Methods The adsorbability of ACF was investigated and the results were compared with that of granular active carbon(GAC).Results The adsorption efficiency of ACF was 93%,the selective adsorbability was 94.28%,the saturation adsorption capacity of gaseous benzene was 25%,as for GAC,they were 88%,88.57% and 12% respectively.Conclusion ACF is better than GAC in the adsorption efficiency of benzene in the condition of low concentration and long time sampling.
