摘要

This research work thoroughly describes the process of obtaining and characterizing iron oxide (Fe3O4) nanoparticles as well as emphasizes how different pH levels, reaction environments and synthesis methods can respectively control its size or activity. Characterization of the crystalline structure, morphology and size of the nanoparticles was carried out. It describes key methods of synthesis such as arc discharge or electrode configuration in electrolyte solutions emphasizing on applied voltage or processing time, which resulted in good quality of nanoparticles, concluding with comparing particle diameters and prepared form of nanoparticles in mentioned methods. In this proposed synthesis mechanism, ferrous and ferric ions are hydroxylated in a controlled anaerobic process to yield Fe3O4 precipitates. Synthesis of the iron oxide (Fe3O4) nanoparticles was found to highly depend on pH parameters, and pH 11 was optimized as the favorable pH parameter based on the results acquired, as it well controls the growth and stability of the particles. The findings highlight the promise of Fe3O4 nanoparticles for various biomedicine and environmental remediation applications where particle stability, magnetic properties and cheap synthesis are crucial.
