Abstract Biomass derived carbon materials have advantages of cost and availability over other carbon materials. However, handful researches based on biomass derived carbon materials have been conducted to explore the oil–water adsorption potential. In this study, we demonstrated that the egg yolk derived carbon material in the presence of iron nanoparticle can be used as a cost-effective absorbent to oil–water separation. Carbon-sponge composite was prepared by dip coating method and showed high adsorption capacity (from 28 to 87 times its original weight) for broad spectrum of organic solvents and oil. These results show evidence that the egg yolk derived carbon material is suitable candidate for the construction of hydrophobic sponge in large-scale and low-cost for removal of oil contaminants from aqueous medium.

1 Introduction One of the most important biological attacks is oily waste water which has been created during extraction, transportation and storage of oil. Marine species and sea grasses can be affected by the harmful effects of oil pollution [1–4]. The oil spill in the sea is more dangerous than that on the land due to floats on the sea surface and spreads over wide areas by waves and wind [5, 6]. So a rapid removal of spilled oil is required in order to prevent oil diffusion into a larger area. There are different reported methods including in situ burning, mechanical collection, chemical dispersants, bioremediation and adsorption for oil spill cleanup [7–13]. Among these methods, absorbent materials are considered to be one of the most effective approaches due to the low cost, easy fabrication, high selectivity, environmental friendliness and good recyclability [14, 15]. Therefore, development of selective hydrophobic absorbent for these pollutions from

water has become a worldwide challenge from view point of environmental and ecological issues. In the first studies, different microporous materials based on silica and carbon materials such as wool, zeolites, activated carbon have been investigated in oil–water separation. But these materials suffered from problems such as low absorption capacity, non-selective water/oil absorption and recyclability [16, 17]. Therefore, design and synthesis of novel hydrophobic or hydrophilic material for selective oil–water separation has attracted great attention in recent years. To address this challenge, many studies have been m
