Problems solved by technology

[0003] At present, activated carbon and carbon nanotubes are the most conventional materials used at present. Although these materials are stable in nature, large in specific surface area, and have a wide range of pore structure distribution, they are used for wastewater treatment. High, and the adsorption rate of carbon nanotubes is slow, and large-scale production cannot be realized. Therefore, it is necessary to urgently develop a new material such as nano-scale graphene that can be used in large-scale production and has better adsorption properties.

Description

technical field [0001] The invention relates to a novel nano-scale graphene high-efficiency oil-absorbing material, in particular to a novel nano-scale graphene high-efficiency oil-absorbing material and a preparation method thereof. Background technique [0002] Due to the leakage of world crude oil and the pollution of industrial organic solvents, the global water pollution problem is becoming more and more serious. According to statistics, nearly 10 million tons of oil enters the water body through various channels every day in the world and pollutes the water body environment. The discharge of this oil pollution has caused fatal damage to rivers, oceans and the ecological environment. Therefore, the research and development of effective oil recovery technology and oily wastewater purification materials have attracted much attention. [0003] At present, activated carbon and carbon nanotubes are the most conventional materials used at present. Although these materials a...
