Abstract
Synthesis of zinc ferrite nanoparticles (ZnFe2O4) of iron ore taken in Tanah Laut has been done. The Synthesis uses the coprecipitation method. ZnFe2O4 nanoparticles were characterized using X-Ray Diffraction (XRD), Transmission Electron Microscopy (TEM), Vibrating Sample Magnetometer (VSM), Fourier Transform Infrared (FTIR), and UV-Vis Spectrophotometer. Using XRD, it was found that ZnFe2O4 has an average crystal size of 8.80 nm. ZnFe2O4 is superparamagnetic because it has a narrow loop area of about 10 kOe.emu/g. Using FTIR, the Zn-O and Fe-O groups were obtained at wave numbers 556.58 and 598.87 cm�1 . The absorption spectrum is in the range of UV light (200 nm) to visible light (600 nm) and at wavelength of 288 nm is observed absorption.
