The Study of the Interaction Mechanism of Linoleic Acid and 1-Linoleyl-2-Oleoyl-3-Linolenoyl-Glycerol with Fe3O4 Nanoparticles

The interaction mechanism of Fe3O4 nanoparticles with linoleic acid and 1-linoleyl-2-oleoyl-3-linolenoyl-glycerol represented by two-layer coordination model has been determined. By means of Fourier spectroscopy, scanning electron microscopy, energy dispersive X-ray spectroscopy, X-ray photoelectron spectroscopy, X-ray phase and thermal gravitational analysis, the interaction mechanism of lipids (linoleic acid and sunflower oil) with Fe3O4 nanoparticles has been studied.

Dissolution Kinetics of Fe3O4 Nanoparticles in the Acid Media

The Fe3O4 nanoparticles dissolution in the acid media (pH = 1.8–5.0; 3 h) has been studied. The kinetic curves have been obtained and Fe3О4 solubility has been determined using spectrochemical, gravimetric and atomic absorption methods. Fe3О4 solubility was found to be increased with the increase in inorganic media acidity and the time. By means of SEM, XRD and NMR analyses the effect of acidic media on the physico-chemical properties of Fe3О4 particles surface has been determined.
