Abstract

The invention relates to a preparation method and application of a bio-based oil solidifying material. The method comprises the following steps: taking wheat bran as a basic material; depositing chemically modified inorganic nanoparticles on the surfaces of the wheat bran; grafting porous polymers on the surfaces of the wheat bran with a free radical polymerization method, so as to obtain a novel oil solidifying material with high oil absorption rate. The bio-based oil solidifying material obtained with the method has the advantages of being low in density, high in oil absorption rate, high in oil solidifying speed, easy in separation of an oil solidifying block from water, and so on, therefore, the bio-based oil solidifying material is a novel efficient oil-water separation material and has the comparatively high practical value and the comparatively good market prospect in the fields of oil overflow, chemicals treatment, etc.

Description

technical field [0001] The invention relates to the field of oil-water separation and the field of water surface oil pollutant treatment, in particular to a preparation method and application of a bio-based oil-condensing material used for water surface oil spill treatment. Background technique [0002] With the development of modern industry, people's demand for petroleum products is increasing year by year. Along with frequent oil exploitation and transportation of petrochemical products, oil spills on the water surface and oil spill accidents occur frequently, causing great harm to the water environment. For example, the oil spill accident in the Gulf of Mexico caused serious ecological disasters. Therefore, dealing with oil spills on water is a significant topic. [0003] Oil condensing material is a chemical treatment agent that can condense the oil spilled in flow state into a solid or semi-solid block. Applying oil-condensing materials to oil spill treatment can qui...
