Petroleum adsorption degradation material and preparation method thereof

Abstract

The invention relates to the field of seawater treatment, and discloses a petroleum adsorption degradation material and a preparation method thereof, wherein the material is a silica-carbon nanotube-kapok fiber derivative composite material loaded with titanium dioxide nanowires. The carbon nanotubes are acid oxidation-modified carbon nanotubes, the kapok fiber derivatives are reduced-treated kapok fibers, and the surfaces of the modified carbon nanotubes and the kapok fibers contain plenty of hydroxyl groups. In the process of forming a silica gel by silica, the hydroxyl groups on the surfaces of the modified carbon nanotubes and kapok cellulose also participate in a network structure of the silica gel, so that oxo-bridged oxygen bonds are used for connection between the silica and the carbon nanotubes or between the silica and the kapok fibers, the rigid carbon nanotubes and the kapok fiber bonds are accessed to a network structure of the silica gel, the oil absorption capacity, strength and aging resistance of aerogel can be greatly improved, and the service life of the aerogel is prolonged.

Description

technical field

[0001] The invention relates to the field of seawater treatment, in particular to a petroleum adsorption degradation material and a preparation method. Background technique

[0002] With the development of industry, the pollution of industry to the environment is becoming more and more serious. In recent years, people's awareness of environmental protection has gradually strengthened, and the government has paid more and more attention to environmental governance. Among the many sources of pollution, water pollution is particularly prominent. Among them, the leakage and discharge of industrial oil have caused huge pollution to oceans and rivers, posing a serious threat to the environment. At present, oil-absorbing materials such as super oil-absorbing resins are generally used to adsorb oil in water bodies. Super oil-absorbing resin is a polymer formed by cross-linking lipophilic monomers, with a three-dimensional cross-linking network structure between mo...
