Abstract
This report attempts to elucidate the potential of plant seed extract assisted synthesis of Graphite based zinc oxide nanoparticles (C-ZnO NPs) towards removal of chromium (VI) ions from the water samples. The Graphene-zinc oxide composites were characterised using TGA, XRD, FTIR and SEM. The C-ZnO nanocomposites have found to remove chromium from the sample through adsorption process. The sensitivity of chromium removal through adsorption is found to be in the range of 40-240 mg. The adsorption behaviour was found to be fitting with Langmuir isotherm model and the adsorption reaction follows pseudo second order kinetics.
