Abstract

Activated carbon was prepared from coconut coir and adsorption of lead from aqueous solution by the activated carbon was examined. Batch adsorption tests showed that extent of lead adsorption was dependent on metal concentration, contact time. p11 and carbon (lose. Adsorption was low at acidic pH and increased with pH. Equilibrium adsorption was attained in 150 min and maximum adsorption occurred at pl-f 5.0. Adsorption of lead by activated carbon füllowed pseudo-second-order kinetics. Adsorption capacity of the activated carbon for adsorption of lead was evaluated by batch equilibrium test and compared with that of' F-400 commercial activated carbon. Coconut coin activated carbon showed higher adsorption capacity for lead [3.63 (Freundlich) and 7.75 (Langmuir)] than that [1.87 (Freundlich) and 7.55 (Langmuir)] of the F-400 activated carbon. Coconut coir activated carbon is a suitable substitute for commercial activated carbon in removal of lead from aqueous solution.
