Preparation method of magnetic bacteria cellulose aerogel oil absorption material

Abstract

A preparation method of a magnetic bacteria cellulose aerogel oil absorption material, and relates to a method for preparing an oil absorption material. The aim of the invention is to provide the preparation method of the magnetic bacteria cellulose aerogel oil absorption material. A bacterial cellulose aerogel is modified into a carbon nanometer fiber aerogel oil absorption material, and magnetic particles are added to the prepared aerogel, so that magnetic substances can be conveniently used for salvage and recovery after oil absorption and are beneficial to collecting. The method comprises the steps as follows: 1, cultivation of bacterial cellulose; 2, preparation of bacterial cellulose aerogel; 3, preparation of the carbon nano fiber aerogel absorption material; and 4, preparation of the magnetic carbon nanofiber aerogel oil absorption material. The invention prepares magnetic carbon nanofiber aerogel from bacterial cellulose, the preparation method is simple, novel in design and environment-friendly, and has good biocompatibility, high absorption efficiency and convenience for fishing, and can be reused for many times.

technical field

[0001] The invention relates to a preparation method of an oil-absorbing material, in particular to a preparation method of a magnetic bacterial cellulose airgel oil-absorbing material. Background technique

[0002] In recent years, with the increasing development of offshore oil resources, oil spill accidents have been increasing. Similar oil spills happen every year in the world. With the acceleration of industrial society, my country's oil pollution is becoming more and more severe. On May 5, 2010, the crude oil spill in the Gulf of Mexico in the United States attracted great attention from the international community. An oil drilling platform on the coast of Louisiana in the southern United States caught fire and exploded at around 10 pm local time on April 20, 2010, causing 7 serious injuries. , At least 11 people are missing. The nearly three-month oil spill not only caused huge economic losses, but also brought lasting and serious pressure to the envi...
