In this century, textile industries have contributed significantly in the release of heavy
metals in the water sources that contributes to water pollution. Thus, the iron oxide
nanoparticles (IONPs) have been used as absorbents for its remediation. It is due to
its special physical characteristics which are inexpensive method, and easy
regeneration in the presence of the external magnetic field that makes it more
attractive as a water purifier. The IONPs were synthesized by using ratio
33%:40%:27% water-in-oil (W/O) microemulsion method and the surface was
modified using oleic acid. Which is used to stabilize the magnetic nanoparticles. The
size, structure, morphology and surface modification were characterized by using X-
Ray Diffraction (XRD), Scanning Electron Microscope (SEM) and Fourier Transfer
Infrared (FTIR). By using the Atomic Absorption Spectroscopy (AAS) the removal of
heavy metal Cu 2+ was studied.
