Development of New Technology for the Removal of Cr^6+ by Magnetic Nanoadsorbents from the Industrial or Sewage Wastewater

The heavy metals pose a serious water pollution problem especially contamination of portable groundwater with heavy metals that cause health hazards also its concentration is high in industrial and sewage wastewater. The main focus of this study to remove heavy metal chromium from contaminated water by using synthesized Iron Oxide Nanoadsorbent (ION). The batch adsorption study was conducted for the removal of chromium along with different parametric studies such Initial concentration of chromium metals, adsorbent dose, pH, contact time and temperature. The employed ION gives positive results, the adsorption of chromium is very rapid and most of fixation occurs at first 30 minutes. The adsorbent was characterized by before and after treatment of Chromium contaminated water, such as SEM-EDS, XRD and FTIR. The adsorption kinetics obeys second order kinetic. The result suggests that ION can be beneficial in chromium removal from the contaminated water.
