Abstract
Iron nanoparticles were obtained in a biologically reaction method using the Beauveria bassiana fungus. X-ray diffraction (XRD), scanning analysis (SEM) and atomic energy microscope (AFM) showed that the characterization of the iron particles was verified, as the average grain size was 13.9 nanometers. The topography and features of the surface were also studied, and it was found that it was somewhat regular. The optical properties of iron oxide were studied using UV/Vis spectroscopy, and the energy gap was found to be (4.8 eV). The FTIR spectrum showed a transverse band at (1640 cm-1) which belongs to the groups of primary amines (N-H) belonging to the Bavaria extract. Other bands appeared at the (3500-3460) cm-1 . This work confirm the effectiveness of the Bavaria bassiana fungus as an aid in the process of preparing iron nanoparticles.
