Abstract

The invention relates to a method for preparing a composite sponge capable of absorbing viscous crude oil, which is prepared by reducing graphene oxide and loading it on a melamine sponge, and adopts the following steps: (1) preparing a graphene oxide dispersion; (2) A certain concentration of ammonia water and L-ascorbic acid are added to the graphene oxide dispersion; (3) the sponge is put into the above solution for hydrothermal reaction; (4) the reacted composite sponge is taken out and dried to obtain graphene Composite melamine sponge. The preparation method of the invention is simple and easy, has good repeatability, does not produce secondary pollution, has a high degree of commercialization of the melamine sponge and is low in price, and the obtained composite sponge can quickly absorb viscous crude oil in water.

Description

technical field [0001] The invention relates to an oil-absorbing functional material, in particular to a method for preparing a composite sponge capable of absorbing viscous crude oil. Background technique [0002] With the development of the oil industry, a large amount of oil flows into the ocean every year due to oil spills from oil fields, pipelines or cruise ship accidents, causing serious pollution to water bodies and coastal environments. The rapid removal of this large area of ​​viscous crude oil and the advanced treatment of secondary organic pollutants are very important but have not been effectively solved. [0003] In view of the characteristics of oil pollutants floating on the water surface and nearby depths, it is an ideal choice to use floating oil pollution removal materials to achieve faster oil pollution treatment and convenient recovery. [0004] As a two-dimensional nanomaterial, since its discovery in 2004, graphene has become a research field in vario...
