Abstract

The present work reported the adsorption of Cr (VI) from aqueous solutions on activated carbon prepared from teak wood waste. Biomass from teak wood were taken out and pulverized in a micro-pulverizing mill. The powder thus obtained was activated with 40% H3PO4 and carbonized at 600 °C for 1 hour in an inert atmosphere. Physico-chemical characteristics such as  functional groups and surface morphology of the activated carbon were analyzed using FTIR spectroscopy and SEM analysis respectively. Batch adsorption experiments were performed to investigate the effects of Cr (VI) concentration, carbon dose, pH and time. The maximum adsorption capacity of Cr(VI) was found to be 1.5 g/L at pH 3 and temperature 30±1 °C. The Freundlich adsorption isotherm best represented the equilibrium data and a pseudo-second order relation represented the adsorption kinetics.
