苯胺对生物体的危害极大，是环境监测的一项重要指标。本文以膨胀石墨为吸附剂，研究了它对苯胺的吸附性能，主要探讨了苯胺溶液的浓度、时间及膨胀石墨粒度对吸附行为的影响。结果表明，膨胀石墨对苯胺具有较好的吸附效果，膨胀石墨对苯胺吸附的最佳浓度是400μg／mL，吸附90分钟就可以达到平衡，而且粒径为0．177-0．149mm的膨胀石墨对苯胺吸附量最大。

Aniline is toxic for organism, which is one of the most important indexes in environmental monitoring. In this paper, the absorption of expanded graphite on aniline was studied. Some factors, including the concentration of aniline solution, time, and the granularity of expanded graphite, were discussed in detail. It was showed that expanded graphite had good adsorption on aniline, with the optimal aniline concentration for expanded graphite adsorption 400μg/mL. The adsorption balance was reached after 90 minutes, and the optimal graphite granularity for adsorption was 0. 177-0. 149mm.
