title: Dissolution Kinetics of Fe3O4 Nanoparticles in the Acid Media
abstract: The Fe 3 O 4 nanoparticles dissolution in the acid media (pH = 1.8-5.0; 3 h) has been studied. The kinetic curves have been obtained and Fe 3 4 solubility has been determined using spectrochemical, gravimetric and atomic absorption methods. Fe 3 4 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 Fe 3 4 particles surface has been determined.
