The effect of ultrasonic treatment of iron oxide and iron oxyhydroxide nanoparticles (ferrihydrite
nanoparticles synthesized by Klebsiella oxytoca microorganisms, ferrihydrite nanoparticles synthesized
by a chemical method and hematite nanoparticles) is studied. Samples of nanoparticles were investigated
using transmission electron microscopy, Mössbauer spectroscopy and X-ray diffraction methods. The for-
mation of the a-Fe metal phase from nanoparticles of iron oxides and iron oxyhydroxides was detected.
The metal phase is formed as a result of the reduction of iron ions during cavitation treatment. According
to the experimental results, the presence of a protein or a polysaccharide component is necessary for the
course of this reaction
