Abstract: Carbon based microporous material is commonly used as sorbent for oil spill incident as they are inexpensive, hydrophobic characteristic, and high sorption capacity. For instance Granular Activated Carbon is commonly used as sorbent in the waste water industry to remove organic contaminant. Exhausted Granular Activated Carbon is recyclable after thermal regeneration at high temperature. 7% PAN/DMF Electrospinning Carbon Nanofiber Membrane has similarity as it is hydrophobic microporous, inexpensive to fabricate. Feasibility of Carbon Nanofiber Membrane to be used as effective oil sorbent has been conducted as to investigate its sorption capacity, and reusability. Sorption study is conducted for Granular Activated Carbon and Carbon Nanofiber Membrane. Result found that Carbon Nanofiber Membrane has higher saturated sorption capacity and longer equilibrium time as compared to Granular Activated Carbon. Sorption results are presented as Linear and Non-linear Pseudo Second Order sorption isotherm. Thermal regeneration for Carbon Nanofiber Membrane and Granular Activated Carbon has been carried out as to identify reusability of sorbents. Regeneration in Nitrogen gas atmospheric at 400 ̊C could sustain the virgin’s saturated sorption capacity after 4 cycles of regeneration for both sorbents.
