结果表明。 由于PACF具有高的比表面积和极为发达的微孔结构，因而比AC具有更高的吸附量与吸附速度。

The results show that the adsorption capacity and adsorption speed of PACF are higher than that of AC because of its high specific surface area and extensively micropore structure.

膨胀石墨对重油的吸附量随着膨胀容积的增大而增加，合适的电流密度、电解液浓度以及反应时间是制备高膨胀容积膨胀石墨的关键。

Adsorption quantity increases with the expanded volume. Appropriate current density, electrolyte concentration and reaction time are the keys to obtain high-expanded volume.

铜离子在吸附量由低到高的过程，首先聚集在孔隙入口处，再逐渐填满孔隙内部空间。

The ions gather in the pore entrance at the start of the adsorption process. Then the ions move into the inner pores and gradually fill the pore space.
