Preparation of Superparamagnetic Fe₃O₄ Nanoparticles from Iron Sand Mediated by Soft Template and Their Performance as Antibacterial Agent
2018
Journal of Magnetics
In this work, the soft-template technique was employed in preparing the superparamagnetic Fe 3 O 4 nanoparticles from natural iron sand. A series of the Fe 3 O 4 nanoparticles formed spinel crystal structure with the particle size in the range of 1.9 to 6.6 nm which was varied by diethylamine concentration as the template. All samples had the functional groups of Fe 3+ -O 2− , Fe 2+ -O 2− and OH and exhibited the superparamagnetic character. The antibacterial activity of the Fe 3 O 4
