Recently, there is a growing necessity to develop environmentally friendly nanoparticle synthesis methods .In this study, we have investigated synthesis of magnetic iron nanoparticles using Sargassum ilicifolium alcoholic extract. The synthesis and characterization of magnetic iron nanoparticles were obtained via UV-Vis spectrum , X-ray diffraction(XRD), transmission electron microscopy(TEM) and vibrating sample magnetometry(VSM) respectively. Formation of iron nanoparticle was attended whit change color from green to green brownish. The maximum peak absorption of synthesized iron nanoparticles was observed at 428 nm indicating the reduction of iron ions and formation of iron nanoparticles. According to the acquired analyses, shape of nanoparticles was spherical and face centered cubic(FCC) and the crystal size was 26.73 nm. Moreover, as prepared iron nanoparticles were demonstrated superparamagnetic and soft magnetic properties.
