Abstract

In this study Super paramagnetic Iron Oxid (Fe3O4) nanoparticles synthesized by sol- gel method. The synthesized nanoparticles are characterized by UV-Visible spectroscopy, TG-DTA, TEM, XRD, EDAX and SEM. Synthesized magnetite nanoparticles are used for removal of highly toxic and mobile hexavalet chromium in the environmental waste water. Magnetite nanoparticles (Fe3O4) are negatively charged and Cr (VI) is positively charged. These charges are determined by the Zeta potential. Cr (VI) and the interaction with magnetite nanoparticles was studied at concentrations (20, 40 ml) and pH (8.2) levels of chromium.
