Modification of granular activated carbon using low molecular weight polymer for enhanced removal of Cu2+ from aqueous solution

Palm shell activated carbon was modified via surface impregnation with polyethyleneimine ( PEI) to enhance removal of Cu2+ from aqueous solution in this study. The effect of PEI modification on batch adsorption of Cu2+ as well as the equilibrium behavior of adsorption of metal ions on activated carb...
