4DescriptionAbstract Activated carbons were produced from Gambeya albida and Telfairia occidentalis seed shells by chemical activation and their properties were determined. The effects of different production conditions (activating agent, carbonization temperature and carbonization time) were studied and it was found that activation with H3PO4 gave carbons with better properties than activation with NH4Cl. Also, bulk density and % yield of the adsorbents decreased while surface area, total pore volume, % weight loss and % ash content increased with increase in carbonization temperature from 300 to 600 oC and carbonization time from 60 to 180 minutes for both raw materials. The potential of removal of Pb(II) ions from aqueous solution by selected activated carbon from both raw materials was also studied and it was found that the adsorption capacity was influenced by the contact time, initial Pb(II) concentration, solution pH, activated carbon particle size and dose as well adsorption temperature.
