摘　　要：膨胀石墨 (Expanded Graphite,简称 EG)是一种新型的碳素吸附剂 ,具有独特的孔隙结构。本文对比了膨胀石墨与聚氨酯吸油材料对浮油的吸油能力和保油能力 ,膨胀石墨与活性炭对乳化油的深度处理的能力 ,并从膨胀石墨的结构、吸附行为等方面具体探讨了产生膨胀石墨超大吸油量的机理。EG(Expanded Graphite) is a new kind of cabonaceous sorption material, which has a particular pore structure. In this paper, the oil sorption ability and oil keeping ability of EG and PV-02(a kind of polypropylene) are studied. The abilities of EG and active carbon to treat waste oil water are also studied. And the mechanism of EG's super oil sorption amount is discussed.
