Essay

The thesis is devoted to developing a method of synthesis of magnetic fluid. The synthesis problems of the magnetic fluids stability were determined, their structural organization and the catalytic activity in oxidation processes were studied. Structural organization of the magnetic fluid was investigated by using modern physicochemical methods (NMR, FMR, impedance spectroscopy), which showed that the fluid has a structure such as core-shell. The catalytic activity of magnetite and substituted ferrites were experimentally proved. The effect of partial substitution of Fe2+ ions in magnetite by ions Cu2+ and Co2+ on its oxidative stability was shown.
