AB - Oil spills into ocean or coastal waters can result in signifcant damage to the environment via pollution of aquatic ecosystems. Absorbents based on reduced graphene oxide (rGO) foams have the capacity to remove minor or major oil spills. However, conventional chemical synthesis of rGO often uses petrochemical precursors, potentially harmful chemicals, and requires special processing conditions that are expensive to maintain. In this work, an alternative cost-efective and environmentally friendly approach suitable for large-scale production of high-quality rGO directly from used cooking sunfower oil is discussed. Thus, produced faky graphene structures are efective in absorbing used commercial sunfower oil and engine oil, via monolayer physisorption in the case of used sunfower and engine oils facilitated by van der Waals forces, π–π stacking and hydrophobic interactions, π-cation (H+) stacking and radical scavenging activities. From adsorption kinetic models, frst-order kinetics provides a better ft for used sunfower oil adsorption (R2=0.9919) and second-order kinetics provides a better ft for engine oil adsorption (R2=0.9823). From intra-particle difusion model, R2 for USO is 0.9788 and EO is 0.9851, which indicates that both used sunfower and engine oils adsorption processes follow an intra-particle difusion mechanism. This study confrms that waste-derived rGO could be used for environmental remediation.
