摘要
目的为将活性炭纤维(ACF)应用到空气中苯的检测中提供基础数据与应用依据。方法进行ACF和颗粒活性炭(GAC)对空气中苯和苯系物的吸附性能试验,并对参数进行比较。结果ACF对1mg/m3的苯气体吸附效率可达93%,而GAC为88%;ACF在复杂气体情况下对苯的选择性吸附效率为94.28%,大于GAC(88.57%);ACF对苯的饱和吸附容量为25%,显著大于所选GAC(12%)。结论对于较低浓度或较长时间的含苯气体采样,ACF具有一定优势。
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.
