Magnetic fluids. Cleaning the water from oil

The main component of the magnetic fluidis fine magnetite, which corresponds to the magnetic characteristics. To obtain adequate dispersion of magnetite we used deposition method magnetite from aqueous solution containing salts of two or ferric iron. The magnetite was investigated by X-ray diffraction analysis and electron paramagnetic resonance spectroscopy. The article is devoted to methods of small dispersal of magnetite, the study of the structure and magnetic characteristics. The article describes a method of obtaining magnetic fluids, the interaction of their components and the dependence of the magnetic properties of the liquid from them. The paper proposes the scheme of technological water from oil by electromagnetic filtration.
