Abstract
In this study, magnetite (Fe3O4) nanoparticles were prepared by the chemical-metallurgy method using such surfactants as sodium dodecyl sulfate (SDS) and disodium salt of ethylenediaminetetraacetic acid (Trilon B). The dispersity, particle size, and magnetic parameters of the resulting powders were studied. The magnetization of Fe3O4 nanoparticles obtained with the addition of SDS and Trilon B was shown to be greater than that of Fe3O4 nanoparticles without the addition of surfactants. The coercivity values were approximately the same for the three cases under study. The use of surfactants has made it possible to obtain magnetite nanoparticles with high magnetization values, which makes them suitable for various applications in biomedicine.
