Abstrakt: The waste water released from industries which contain pollutants like heavy metals, dyes and other toxic chemicals brings numerous harms to the ecosystem and humans. Nowadays the nanocomposites based technologies are effectively used for environmental remediation. In the present study, hexavalent chromium was removed from the industrial effluent using magnetite carbon nanocomposite. The nanocomposite composed of highly porous carbon and iron oxide nanoparticles prepared by using agrowastes (sugarcane bagasse and orange peel extract). Iron oxide nanoparticles (FeONPs) formation was confirmed by UV-visible spectroscopy; incorporation of magnetite with highly porous carbon was established by Fourier Transforms Infrared Spectroscopy and X-ray Diffraction Spectroscopy. Morphological features of magnetite nanoparticles and highly porous carbon were analyzed using Scanning Electron Microscope and Transmission Electron Microscope. Magnetic properties analyzed by Vibrating Sample Magnetometer revealed magnetite carbon nanocomposite exhibited better Ms value than highly porous carbon. The concentration of Cr 6+ in treated effluent was determined using Atomic Absorption Spectroscopy. Pseudo-second order equation fitted with kinetics and the Langmuir monolayer favors for isotherm. This study reveals efficiency in Cr 6+ removal from effluent using magnetite carbon nanocomposites which extends their application in waste water treatment.
