Abstract
The controlled morphological of magnetic nanoparticles have gained great importance in a wide variety of applications due to their promising physico-chemical properties. Therefore, in this study, barium hexaferrite (BaFe12O19) nanoparticles were prepared with the simplest and most efficient chemical route, the two-step sol–gel method, in the presence of seven different and widely used surfactants. The aim of this research is to investigate the influence of the different surfactants on the morphology and particle size of the BaFe12O19 nanoparticles; therefore, different techniques were employed in order to elucidate the composition and structure of the BaFe12O19 nanoparticles such as XRD, SEM, FT-IR, and EDX. The magnetic properties were investigated by measuring the hysteresis loops. In order to investigate the role of BaFe12O19 nanoparticles as the photocatalysts, decolorization of methyl orange under ultraviolet light irradiation was also evaluated. In addition, the purity of decolorized water was examined by investigating its effect on the health condition of liver of rats.
