Abstract

The invention discloses a method for preparing carbon-copper-coated ferroferric oxide composite magnetic oil removal particles. The method comprises the following steps of modifying ferroferric oxide,introducing a carbon source, adding a lubricant, an emulsifying and thickening agent and a stabilizer, and then carrying out heat treatment so as to prepare the Fe3O4@C / Cu composite magnetic oil removal particles. The method has the advantages that the technical problems that a floating oil cleaning technology is tedious in preparation process, incapable of realizing mass production and the likecan be solved; and the particles prepared through the method is high in surface carbonization degree and stable in carbon layer, mass production can be realized, and the good particle preparation method solves the problem of floating oil on the water surface.

Description

Technical field: [0001] The invention belongs to the field of nanometer preparation, and in particular relates to a method for preparing carbon copper-coated ferric oxide composite magnetic degreasing particles. Background technique: [0002] During the production, transportation, storage, refining and use of petroleum, it will cause environmental pollution, especially water surface pollution. With the increasingly stringent water quality standards and regulations, the cleaning technology of oil slicks on the water surface has become more and more comprehensive. However, it is still a technical problem to effectively solve large-area oil layers with a thickness less than 50 μm. Nano-iron oxide materials that have high hydrophobicity and high lipophilicity through surface modification or combination with functional materials and can overcome viscous resistance, surface tension and gravity to recover from water surface under external magnetic field have become the first choice...
