NOVELTY - Method for recovering high-viscosity oil spill using a graphene-based material, involves (a) immersing melamine sponge in graphene oxide dispersion liquid, and after a few seconds, taking out and drying to obtain melamine sponge-graphene oxide material, and reducing the material by using a reduction method to obtain graphene-based melamine sponge-reduced graphene oxide material, and (b) building a platform for adsorbing oil spill, adding 500-1000 ml seawater to the beaker, adding 1-10 g viscous crude oil to the seawater, increasing the temperature of the viscous crude oil on the sea surface above 60 degrees C by light, reducing the viscosity of crude oil to below 100 mPa.second, adding graphene-based melamine sponge-reduced graphene oxide material to the seawater, and realizing the full removal and recovery of oil spill in the seawater system. USE - The method is used for recovering high-viscosity oil spill using a graphene-based material. ADVANTAGE - The method is simple, easy to realize, cost-effective, and environmentally friendly, and reuses the graphene-based material many times. The method realizes the recycling of high-viscosity oil spill in a cheap, environmentally-friendly and efficient manner, and achieves rapid, full and complete adsorption of crude oil through the synergy of light and graphene materials.
