Palm shell is used as the main raw material for activated carbon production, which purchased from a local oil palm mill at Pahang, Malaysia. The surface area and pore diameter of the produced activated carbon was measured by Brunauer, Emmett and Teller (BET) theory. All characterization of produced activated carbon was ensured that it is highly efficient. Finally it is tested in vitro to determine its adsorbing capacity as an antidote for paraquat as a toxin.
