Аннотация: Ferrihydrite nanoparticles formed as a result of the microorganism activity have been studied using Mossbauer spectroscopy, X-ray powder diffraction analysis, and X-ray fluorescence analysis. Three positions of trivalent iron with nonoverlapping ranges of quadrupole splittings have been revealed in bacterial ferrihydrite: QS{Fe(3+)Показать полностью(1)} = 0.49-0.83 mm/s, QS{Fe(3+)(2)} = 0.84-1.10 mm/s, and QS{Fe(3+)(3)} = 1.25-1.73 mm/s. It has been experimentally demonstrated that the Fe(3+)(3) positions are the centers of nucleation of the hematite phase in the course of heat treatment.
