Magnetic fluid for the removal of water-shedding oil, method for producing the same, and method for removing and recovering water-shedding oil using the same

摘要

The present invention relates to a magnetic fluid which can be used for effectively removing and recovering oil circulated on a water surface, a method for producing the magnetic fluid, and a method for removing and recovering water from a water surface.;The magnetic fluid for removing sleeping oil mist of the present invention is prepared by adsorbing a surfactant on the surface of magnetic fine particles such as magnetite produced from an acid waste liquid and then dispersing the surfactant in an organic solvent to prepare a magnetic fine particle dispersion, /RTI ;The magnetic fluid of the present invention has improved dispersibility with respect to water-shedding oil. Further, by using the oil-based dispersion medium fluid of the present invention, it is not necessary to use a large amount of the water-absorbing material for removing the water-shedding oil, and it is possible to selectively remove and recover only the water-It is environmentally friendly because it does not need to spend a lot of time and time with large equipment for oil separation and it does not adversely affect marine habitat.
