A study on the removal of heavy metal ions using activated carbon is performed. Heavy metal ions tested were Hg, As, Cr, Cd and Pb ions. Variations of pH, shaking time, temperature and coexisting ions were major experimental parameters. The optimum pH range for removal of metal ions were 1-3 for Hg, 5-6 for Cr and As, above 8 for Cd and above 5 for Pb, respectively. Removal of Hg, Cr and As were proceeded by adsorptivity of active carbon, however, Cd and Pb were removed by precipitation reaction.
