Abstract

Magnetic expanded graphite (MEG) composite was synthesized by the explosive combustion method using black powder. The expanded volume and specific surface area (S_BET) of the expanded graphite (EG) were 300.0 ml/g and 34.8 m²/g, respectively. The sorption behavior of the EG/Fe₃O₄ composite was examined in terms of its ability to remove heavy oil, engine oil and diesel oil from water. The liquid hydrocarbon sorption behavior of EG enhanced with iron oxide nanoparticles (Fe₃O₄) was studied. Moreover, black powder combustion resulted in an accordion-like three-dimensional porous structure of MEG, which endowed it with a high sorption capacity (87.70 g/g; heavy oil), good recovery (88.85% recovery after 3 repeat cycles; engine oil) and high regeneration (95.53% after 3 sorption-recovery cycles; engine oil).
