A composite absorbent filter media having adsorption and/or absorption properties for the filtration of ester oils from a liquid includes a graphene and/or graphite composite mixed into a final emulsion, which is subsequently heat treated or cured, cooled, compressed, and dried. The resultant adsorption/absorption media is then disposed within a plug structure having an ingress and egress for liquids mixed with ester oils to pass through. Alternatively, the resultant adsorption/absorption media is disposed into a fabric and formed as a wall used to enclose oil-filled equipment. The media adsorbs/absorbs the ester oils from the liquid, while allowing the liquid to disperse and pass through.

A composition for temporarily-hydrophobic and oil-absorbent powder. The present invention cleans and neutralizes oily and toxic substances from items in water of bodies of water such as ocean floors or along the surface of bodies of water. The present invention initially repels water or water-based substances and then absorbs oil-based substances. The composition includes a quantity of quicklime, a quantity of oil, a quantity of earthworm enzymes, a quantity of water, a quantity of detergent, and a quantity of rubbing alcohol. The quantity of quicklime, the quantity of oil, the quantity of earthworm enzymes, the quantity of water, the quantity of detergent, and the quantity of rubbing alcohol are heterogeneously mixed into an absorbent slurry blend.

Disclosed are a sorbent produced by recycling waste paper, which is an eco-friendly recycling paper resource, to adsorb and remove a marine spilled oil and other types of oil and a method of producing the same. The oil sorbent is produced by hydrophobizing a biomass material such as waste paper using a gas-grafting method. Compared to the oil sorbent of the prior art formed of synthetic resin, it is possible to provide excellent oil adsorption selectivity, a high oil adsorption rate, and a low water absorption rate. Therefore, an incineration process for processing the waste oil sorbent after use is easy advantageously. The oil sorbent generates less harmful substances during combustion because the eco-friendly material is used. Since a biomass material is hydrophobized using vegetable fatty acids, decomposition is performed fast within a short time in a landfill process, and there is no risk of environmental pollution.

Construction for absorbing a fluid, for example, a liquid or gaseous, organic chemical, has an extended web, fabric, yarn or foam member and associated with the extended web, fabric, yarn or foam member is a water-insoluble polymer. The water-insoluble polymer can absorb the fluid organic chemical, and the construction provides for contact of the water-insoluble polymer with the fluid organic chemical when deployed in an environment where the fluid organic chemical may be present for absorption. The construction may be employed in aquatic, aqueous, or dry environments, as a blotter, a wipe or sponge, a filter, in a cartridge, and so forth.
