摘要： 为循环利用植物油淋洗修复多环芳烃污染土壤,应用吸附过程去除植物油中的多环芳烃.对10种吸附剂进行吸附柱和批处理筛选实验,评价了这些吸附剂的物理化学性质,从中筛选出最适合的吸附剂.动态吸附柱筛选实验表明,植物油中的多环芳烃在活性炭F400及F300上的吸附量最高,分别为55.39μg.g-1和23.82μg.g-1,说明吸附剂的粒径对吸附效果有重要影响,而多环芳烃在其他几种吸附剂上几乎没有吸附.批处理筛选实验表明,多环芳烃在两种活性炭上的吸附量仍然最多,分别为211.85μg.g-1和203.79μg.g-1.

Abstract: To recycle the plant oil for remediation of the soil contaminated by polycyclic aromatic hydrocarbons (PAHs) which are contained in the oil, an adsorption process was employed to remove PAHs. Both column and batch adsorption experiments were conducted to screen the most suitable adsorbents from 10 possible ones via the evaluations of their physical and chemical properties. The results of dynamic absorbing column experiments showed that activated carbons F400 and F300 as adsorbents have the highest absorbabilities for PAHs from the plant oil, i. e. 55.39 μg ·g-1 and 23.82 μg · g-1, respectively. The fact reveals that the particle size of adsorbent has imported effect on PAH absorption, whereas the other adsorbents could hardly absorb PAHs from the plant oil. The results of batch adsorption experiments also showed the two kinds of activated carbons have the highest PAH absorbabilities, i.e. 211.85 μg·g-1 and 203.79 μg · g-1, respectively.
