Abstract

The potential of chemically carbonized vitex negundo stem (VNC) for the effective removal of Pb(II) ions from aqueous solution has been investigated in batch experiments. The activated carbon prepared from VNC modified with activating agent H2SO4. Lead adsorption significantly depends on the initial concentration of Pb(II), pH, adsorbent dosage, particle size and effect of temperature. FTIR were used to characterize the functional group and XRD has a highly porous structure with sharp edges. The powder XRD data active sites present in VNC-1. That the main structures of activated carbons are amorphous as expected. The optimum conditions for adsorption studies are calculated and it concludes that the activated carbon exhibits a good adsorption potential for lead ions. The results indicate that the carbon prepared from VNC-1 activated could be used to effectively adsorb lead (II) ions from aqueous solutions.
