摘要：
Sorption of high-viscosity engine oil on exfoliated graphite was performed using two exfoliated graphite samples of different properties for investigations. The oil was removed from the exfoliated graphite by soaking with cyclohexane. Amount of solvent and extraction time were changed to establish the best conditions for oil removal (60-70% by soaking with cyclohexane for 1 h). Regeneration efficiency was measured for a few cycles of oil sorption. Although sorption capacity of exfoliated graphite decreases with the number of oil sorption cycles, efficiency of oil removal is rather high.
