Abstract

The invention relates to a method for preparing composite sponge capable of absorbing viscous crude oil. Graphene oxide is subjected to reduction, and after reduction, the graphene oxide is loaded onmelamine sponge, and the composite sponge is obtained. The method comprises the steps that (1), graphene oxide dispersion liquid is prepared; (2), ammonium hydroxide of a certain concentration and L-ascorbic acid are added into the graphene oxide dispersion liquid; (3), the melamine sponge is put in the mixed solution for the hydrothermal reaction; (4), after the reaction, the composite sponge istaken out for drying, and the composite graphene melamine sponge is obtained. The preparation method is simple, easy to implement and good in repeatability and cannot produce secondary pollution, themelamine sponge is high in commercialization degree and low in cost, 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 sea every year due to oil spills in oil fields, pipelines or accidents on cruise ships, causing serious pollution to water bodies and coastal environments. The rapid removal of such a 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, graphene has become a research topic in various fields due to its superi...
