摘要： 膨胀石墨内部的孔隙结构使其具有优良的吸附性能，尤其对油类分子吸附效果显著。以柴油和萃取自含油污泥中的油品，配制模拟油田厂区内的含油废水，探究油与膨胀石墨质量比、吸附时间和pH等条件对膨胀石墨吸附油效果的影响，找出了膨胀石墨吸附柴油的最佳条件：油与石墨质量比为50∶7、搅拌时间10 min，无需调节pH；吸附重油的最佳条件：油与石墨质量比为50∶8、搅拌时间10 min，无需调节pH；膨胀石墨对油品吸附符合分配吸附规律。

Abstract: The pore structure inside the exfoliated graphite makes it have excellent adsorption performance, especially for the adsorption of oil molecules. Oily wastewater from simulated oilfield plant was prepared with diesel oil and oil extracted from oily sludge. The effects of mass ratio of oil to expanded graphite, adsorption time and pH on oil adsorption by expanded graphite were investigated. The optimum conditions for the adsorption of diesel oil by exfoliated graphite are as follows: the mass ratio of oil to graphite is 50∶7,the stirring time is 10 minutes, without adjusting pH.The optimum conditions for heavy oil adsorption are as follows: the mass ratio of oil to graphite is 50∶8, the stirring time is 10 minutes, without adjusting pH; and the adsorption of expanded graphite to oil conforms to the distribution adsorption law.

Key words: Expanded graphite, Oily wastewater, Influencing factor, Adsorption model
