Synthesis and Characterization of NiFe2O4 Magnetic Nanoparticles using Co-Precipitation Method and Dye Removing from Wastewater

In this present work, synthesis and characterization of soft NiFe2O4 magnetic nanoparticles (MNPs) have been synthesized using co-precipitation method. The prepared nanoparticles were characterized. XRD, result confirmed that the samples have cubic (a=5.0342 A∘) structure and the size of particles were 35 nm. The Morphology and the quantitative analysis of the prepared particles were studied by using SEM spectrum. The FTIR was used to study the presence of functional groups. Finally, the magnetic properties of the powders have been studied by investigating dye removing of aqueous solution at room temperature. The absorbance of samples was measured using a UV-Vis spectrophotometer. Results show that, by increasing the concentration of photo catalyst, the amount of pollutant dye removal of Malachite Green will increase.
