膨胀石墨(简称EG)是通过将残留石墨层间化合物(简称GIC)快速加热到约1000℃而分解、膨胀制得的。这种材料具有较大比表面积和较强表面活性,因此,EG可以吸附重油和粘稠性有机液体。本文综述了清华大学研究组近年来所进行的膨胀石墨吸附重油和生物体液的研究成果。
Expanded graphite (abbreviated as EG) is produced by rapidly decomposing and expanding a residual graphite intercalation compound (referred to as GIC) to about 1,000 ° C. This material has a large specific surface area and a strong surface activity, therefore, EG can absorb heavy oil and viscous organic liquid. In this paper, the research results of the adsorption of heavy oil and biological fluid by expanded graphite in recent years by Tsinghua University research group are summarized.
