Natural clay is a porous material that has the ability to adsorb as well have exchangeable ions with ions from the outside. In this study, the clay used comes from the District Tualang - Perawang Siak Riau Province. This study aims to determined the extent effectiveness of potential clay that can be used to reduce heavy metals in the leachate generated by the landfill (TPA). Treated clay by physics and chemistry, refined clay is used to reduce heavy metals (Pb, Cd and Fe). Analysis of heavy metals used AAS (Atomic Absorption Spectrometry). This study showed a change in acidified clays in terms of adsorption. It was characterized by a change in specific surface area was initially 47.8 m2/g after activation increased to approximately 64.8 m2/g, which will greatly affect the magnitude of the absorption capacity of the adsorbent. The effectiveness of adsorption of the heavy metals analyzed stood at 66 to 78.8 % a high rate.
