Abstract: Sorption kinetics of various oils with different viscosities from 0.001 to 0.850Pa•s into exfoliated graphite column was characterized by measuring sorptivity (effective sorption coefficient) KS and saturated amount of sorption msat. A strong dependence of sorptivity KS on viscosity of oils was observed. Saturated amount of sorption msat into the column was almost a constant of 50kg/kg, which was a little bit smaller than that measured by direct soaking of a lump of exfoliated graphite in oils, due to the presence of a gradient of sorbed oils along the height of exfoliated graphite column.
