摘要

In this work, flake like carbon/AlOOH composite has been synthesized and evaluated as a new adsorbent for the removal of Cr(VI) from synthetic wastewater. Different characterization tools such as, SEM, EDAX, XRD and XPS were performed to characterize the composite material. Batch adsorption studies for Cr(VI) removal were performed under the influence of various operational parameters such as solution pH, contact time, initial solution concentration and temperature. Results obtained revealed that adsorption of Cr(VI) onto carbon/AlOOH composite followed the pseudo-second order kinetics and Freundlich isotherm model. Thermodynamic results suggests that adsorption of Cr(VI) onto carbon/AlOOH composite was spontaneous and endothermic in nature.
